Through the investigation and study of engineering examples, we can understand the problems existing in the implementation of "Technical Code for Design and Construction of Landslide Prevention Engineering", collect the technical data of landslide prevention engineering at home and abroad, analyze and summarize them, and improve the problems existing in the original relevant codes and new technologies and methods in China; Hold expert consultation meetings and seminars, and revise and improve the specifications by collecting expert opinions.
On the basis of respecting the main clauses of the original code, this code revision is based on the original code and some basic data obtained by the Institute of Survey and Technology of Chinese Academy of Geological Sciences in experiments and work practice. It has checked and revised the relevant geotechnical parameters and design and calculation standards (especially the seismic design and calculation standards) in the original code, added some new technologies and methods, and revised and supplemented some mistakes and omissions in the original code.
The new technology and method increase the content of "embedded anti-slide pile", and revise the design and construction of drainage engineering, anti-slide pile, prestressed anchor cable, lattice anchorage, anti-slide retaining wall and other related content, monitoring and acceptance of landslide engineering.
Chapter *** 15 of the revised code includes the scope, normative reference documents, basic provisions of landslide prevention and control engineering design, landslide classification and prevention engineering investigation, landslide prevention and control engineering classification and design safety factor, drainage engineering, anti-slide piles, embedded anti-slide piles (adding technical methods), prestressed anchor cables, lattice anchorage, gravity retaining walls, other prevention and control projects, landslide prevention and monitoring, construction organization and quality.
Second, the scope of application and application examples
The Technical Code for Design and Construction of Landslide Prevention and Control Engineering stipulates the basic provisions of landslide prevention and control engineering design, landslide classification and prevention engineering investigation, landslide prevention and control engineering classification and design safety factor, drainage engineering, anti-slide pile, embedded anti-slide pile, prestressed anchor cable, lattice anchorage, gravity retaining wall, grouting reinforcement, load reduction by brushing, backfilling foot pressing, plant protection, landslide prevention and control monitoring, construction organization, quality inspection and engineering acceptance.
This specification is applicable to guide the design of landslide prevention and control projects. It has played an important role in the design and construction of geological disaster control and landslide prevention engineering, and has been widely adopted by various exploration, design and construction units, which has played a certain guiding role in the prevention and control of geological disasters.
Third, promote the transformation mode.
The Technical Specification for Design and Construction of Landslide Prevention Engineering is determined by the Ministry of Land and Resources and China Geological Survey and implemented as a mandatory standard or recommended standard. It is applied to the design and construction of geological disaster control, especially landslide prevention project, and necessary meetings and personnel training are carried out.
