Present situation of traffic engineering test and detection in China
Test detection is not only an important content of engineering quality control and management, but also plays an important role in traffic engineering construction. In recent years, with the vigorous development of transportation infrastructure projects, China's experimental testing institutions have also developed well. At present, there are more than 80 experimental testing institutions with comprehensive Grade A and special qualifications, and more than 0/000 experimental testing institutions with Grade B and C qualifications, with hundreds of thousands of employees. At present, China is in a period of vigorous development of transportation infrastructure. "Eleventh Five-Year Plan" is not only a crucial period for building a well-off society in an all-round way, but also a crucial period for realizing the new development of China's traffic engineering construction. The main task of traffic engineering construction in China is to speed up the construction of expressway network and rural highway network, so there is still a lot of room for development and progress in experimental detection, and the experimental detection system in China needs constant innovation. However, there are still some unfavorable factors in the current test and detection work, such as the shortage of traffic engineering talents, the serious shortage of test and detection personnel, and the shortage of professional leaders and skilled high-quality professionals. At the same time, there are still some problems in the testing market, which can not be ignored. [ 1]
Problems existing in traffic engineering test and detection in China
3. 1 Insufficient quantity and quality of testing personnel.
In recent years, China has trained a large number of testing personnel, but not all of them are engaged in testing, and many are engaged in management or other positions. In addition, the overall quality of testing personnel is not high, there are not many high-quality talents with high academic qualifications and titles, and many testing personnel are not strong in comprehensive quality. Some testers have just graduated from school and have no practical experience, so it is difficult to complete the testing work.
3.2 Testing and testing market management system is backward
At present, China's current experimental testing market management system is not suitable for the competitive mechanism of socialist market economy. The internal management mechanism of inspection and testing institutions is not only lack of vitality, but also the operating mechanism is aging, which can't follow the objective development law of market economy and doesn't meet the requirements of the development of domestic and international situation and the transformation of government functions. Moreover, the inspectors lack the corresponding sense of service and market competition. In addition, testing institutions are not independent, and the quality of their managers and technicians is often subject to internal and external financial, commercial or other pressures, and the testing results are interfered and unfair.
3.3 Closed and backward detection information does not meet the requirements of advanced and efficient information management.
There is a lack of corresponding information communication channels among experimental testing institutions in the province, and a modern information transmission system has not been established. The corresponding management department can not grasp the timely information, test data and on-site engineering quality trends of all test and testing institutions at any time and anywhere. On the contrary, the testing institutions can't keep abreast of the latest developments of the government, the latest laws and regulations, and the updated information of testing standards and specifications, and the resources among the testing institutions can't be shared. [2]
3.4 The existing test institutions in China are not suitable for the traffic engineering test scale.
Although there are enough traffic engineering testing institutions in China at present, some laboratories are semi-paralyzed, mainly referring to the central laboratories of some construction units and small laboratories of some local units. The ability of these laboratories to carry out comprehensive testing is relatively weak, which can no longer meet the growing needs of transportation infrastructure construction.
Countermeasures to solve the problems in traffic engineering test and detection
4. 1 Improve the quality and professional technical level of test and detection personnel.
At present, the technical level of construction units in various parts of China is mixed, especially the test and detection personnel are not only short of manpower, but also of low quality, which can not meet the needs of practical work. Without a high-level quality inspection team with high professional quality, it is difficult to improve the quality of traffic engineering. Therefore, it is necessary to strengthen the training of testers, improve the quality of testers in an all-round way, and adopt different training methods according to different training objects: First, continue to strengthen the training of testers' professional post skills; Secondly, it is necessary to carry out follow-up education for those who have been engaged in test and detection, such as the study of laws and regulations related to traffic engineering construction and test and detection regulations, and the study of new standards and norms for test and detection. Finally, the staff engaged in special testing should be trained in professional skills, and strict quality self-inspection should be carried out in the actual testing work to strengthen quality management and quality supervision. In addition, it is necessary to strengthen the quality awareness of relevant personnel and implement the responsibility to individuals.
4.2 Department leaders at all levels pay more attention and strengthen supervision.
Leaders of departments at all levels should attach great importance to the test and detection work, establish and improve the test and detection network, strengthen the guidance of test and detection institutions, put forward overall guidance on the purchase and layout of large-scale test and detection equipment, and scientifically allocate personnel and test instruments and equipment in strict accordance with relevant requirements. It is also necessary to establish and improve corresponding laws and regulations, improve quality inspection institutions and engineering quality control management system, and provide substantial guarantee for improving the quality of traffic engineering in China. In addition, it is necessary to further clarify the management responsibilities and inspection functions of quality supervision institutions at all levels in provinces and cities, and implement unified leadership and hierarchical management in administration. All testing institutions should also strengthen their own internal management, establish and improve the testing quality management system, and adhere to the working principle of "quality first, data shall prevail". When carrying out the test and inspection work, the test and inspection institutions should strictly follow the current relevant national standards and norms, adhere to principles in their work, avoid the influence of administrative intervention and external factors as much as possible, adhere to a fair working position, and make a comprehensive, accurate, scientific and reasonable evaluation of the project quality in a realistic way, fully embodying the fairness and authority of the test and inspection work.
4.3 Strengthen the test comparison between testing and testing institutions.
The accuracy of test results is directly related to the quality of traffic engineering. In view of the fact that some measuring instruments and equipment in inspection and testing work are not suitable for the current national quality standards, it is necessary to strengthen the comparison tests among various inspection and testing laboratories. During the laboratory comparison test, an organizational unit prepares the corresponding reference samples, and then distributes the reference samples to the participating units, and carries out the operation test according to the given test operation index. Then the experimental results are sent to the institutions for statistical analysis, and finally the accuracy of the experimental results of each experimental testing institution is determined. Through the comparison test, we can comprehensively check the test environment, the operating proficiency of the test operators and the test instruments and equipment. Comparison test is a very effective method to measure the technical level of testing institutions, which can determine the accuracy of test results and ensure the effectiveness and accuracy of test work. [3]
To sum up, there are still various problems in traffic engineering test and detection in China at present, which need our attention. Nowadays, people have fully realized the importance of engineering quality. Therefore, as an effective measure to control the project quality and the only effective means to test whether the project quality is qualified, the test and detection work needs to attract people's attention. Therefore, how to carry out the test and how to improve the engineering quality by test detection has become the focus of attention. To solve the problems existing in traffic engineering test, we should not only improve the comprehensive quality of employees, but also strengthen the supervision of test and promote the smooth development of test and detection.
