Mao Yisheng was born in 1896. Mao Yisheng was studious and enterprising since childhood, and was good at independent thinking. When he was 10 years old, a dragon boat race was held in his hometown during the Dragon Boat Festival. All the people watching the game stood on Wende Bridge. Because there were too many people, the bridge collapsed and killed many people. This unfortunate incident weighed heavily on Mao Yisheng's mind. He secretly made up his mind that when he grew up, he must build the strongest bridge. From then on, whenever Mao Yisheng saw a bridge, whether it was a stone bridge or a wooden bridge, he always saw enough from the deck to the bridge column. After Mao Yisheng went to school, he saw articles and paragraphs about bridges from books, so he copied them in his notebook. When he saw pictures about the bridge, he cut them out and pasted them on. After a long time, he accumulated several thick notebooks.
After graduating from high school, Mao Yisheng was admitted to the Department of Civil Engineering of Tangshan Institute of Technology. After graduating from Tangshan Road Mine 19 16, he was sent to the United States for postgraduate study with the first place, and set off for Cornell University in September. Who knows that Qi Sejia, director of the school's registration office, proudly said: "This school in Tangshan, China has never heard of it, and it must pass the exam to register." After the examination, Mao Yisheng got excellent grades, so he applied for the postgraduate of bridge major. Since then, Tangshan Road and Mine School has been sent to Cornell University in the United States for graduate study without examination. Mao Yisheng 19 17 received a master's degree from Cornell university, and 19 19 received a doctorate in engineering from Calgary-Mellon Institute of Technology. The title of the doctoral thesis is "The Secondary Stress of Bridge Mechanics", which was first-class in the world at that time, so it won the gold medal awarded by Gariji Institute of Technology. 191912 Mao Yisheng, 24, resolutely returned to China. He is a professor at Tangshan College of Jiaotong University. Mao Yisheng said: "Looking back on my study and life, this 14 year effort is like building a bridge, which has built a solid pier for my lifelong career." After returning to China, Mao Yisheng successively served as a professor of Tangshan Institute of Technology, a professor and director of engineering at Nanjing Southeast University, the president of Hohai University of Technology, the president and professor of Tianjin Beiyang Institute of Technology, the director of Jiangsu Water Resources Bureau, the general manager and chief engineer of China Bridge Corporation of the Ministry of Communications, and the president of China North Jiaotong University.
Mao Yisheng thinks: There are some bridges on the Dachuan River in China, but they are all made by foreigners: Jinan Yellow River Bridge is made by Germans, Bengbu Huaihe River Bridge is made by Americans, Harbin Songhua River Bridge is made by Russians (now belonging to Russia), Yunnan Hekou herringbone Bridge is made by French, Shenyang Hunhe Bridge is made by Japanese ... Qiantang River Bridge, and we in China have to build it ourselves, which proves that we in China have the ability to build this modern bridge. In this way, Mao Yisheng started the overall design of Qiantang River Bridge.
1933 to 1937, Mao Yisheng was the director of Qiantang river bridge engineering department, and presided over the construction of the first modern bridge with both highway and railway functions in China-"Qiantang river bridge". He solved the technical problems in bridge construction by "water injection method", "caisson method" and "floating method". Since then, Mao Yisheng has traveled all over the country, and his name has remained all over the country with the newly-built bridge. After five years' efforts, Mao Yisheng finally built the modern Qiantang River Bridge. When the reporter interviewed Mao Yisheng, he said: "From 19 19 12, I returned to China to serve the society. During the 64-year journey, the most striking thing I did was to host the construction of Qiantang River Bridge. "
From 1955 to 1957, Mao Yisheng was the chairman of the Technical Advisory Committee of Wuhan Yangtze River Bridge, and he accepted the task of building the first Yangtze River Bridge in China. 1September 1955, the bridge was officially started and completed on September 25, 1957, two years ahead of schedule. 19571June15th, the Wuhan Yangtze River Bridge was opened to traffic. This bridge, designed by Mao Yisheng, is a double-deck copper truss bridge for both railway and highway. The upper floor is a highway bridge with a width of 22.5 meters, of which the roadway width is 18 meters; The lower floor is a railway bridge with a width of 18m. The length of the main bridge is 1 155.5m, and the total length is 167O.4 together with the highway approach bridges at both ends. The bridge connects Jing-Han Railway and Yue-Han Railway, becoming the traffic artery running through the north and south of China, connecting the three towns of Wuhan into a whole, and ensuring the integration of the north-south railway and highway network in China.
During the construction of the Great Hall of the People from 65438 to 0958, Premier Zhou Enlai pointed out: "Mao Yisheng's signature is needed." The leadership of the Party trusts Mao Yisheng very much, and Mao Yisheng is extremely responsible for the Party's work. He made a comprehensive review and accounting of the structural design of the Great Hall of the People, and finally signed it.
Mao Yisheng studied, built and wrote bridges all his life. Published more than 200 articles in Chinese and foreign newspapers and periodicals. He presided over the compilation of "Technical History of Ancient Bridges in China" and "Bridges in China-From Ancient Times to the Present" (in Japanese, English, French, German and Spanish). He is the author of Qiantang River Bridge, Wuhan Yangtze River Bridge, Selected Works of Popular Science in Mao Yisheng (I and II) and Mao Yisheng's Works.
Mao Yisheng, director of Railway Research Institute after liberation, president of Railway Institute and vice chairman of National Association for Science and Technology. Since 1954, he has been elected as a member of the first to fifth China People's Political Consultative Conference, a deputy to the National People's Congress and a member of the National People's Congress Standing Committee (NPCSC). Mao Yisheng has made outstanding contributions to bridge construction in China and the world.
