He is one of the pioneers of geology in China, founded geomechanics, and made important contributions to the development of petroleum industry in China. In his early years, he had a superb study on Odonata fossils and their stratigraphic stratification significance. It is suggested that there are Quaternary glaciers in eastern China. This paper studies the crustal movement and its relationship with mineral distribution from the mechanical point of view, and establishes new concepts of geomechanics and tectonic system. Throughout his life, he advocated studying the occurrence, development and combination of geological structures from the perspective of mechanics, and believed that various structural characteristics were the result of in-situ stress activities, and established the concept of "structural system" and geomechanics school. The discovery of Daqing and Shengli oil fields confirmed that the tertiary subsidence of Neocathaysia has broad oil and gas exploration prospects. It creates a method of earthquake prediction by combining active structure research with in-situ stress observation. Astronomy, Geology and Paleontology published in his later years had a far-reaching impact on the interdisciplinary advocacy in China. It has made great contributions to the development of geological education, geological science and geological undertakings in China. 1955 was elected as a member of China Academy of Sciences. He is the author of The Main Causes of Image Changes on the Earth's Surface, China North Training Project, China Geology, Lushan Mountain in the Ice Age, Introduction to Geomechanics and Anthology of Astronomy, Geology and Paleontology. 1971On April 29th, Li Siguang died of illness at the age of 82.

1934 graduated from Shanghai jiaotong university, 1935 went to MIT to study abroad, got a master's degree the following year, and then entered California institute of technology. 1939 after receiving his doctorate in aviation and mathematics, he stayed in school to teach, engaged in applied mechanics and rocket and missile research. 1955 After returning to China, he served as director of the Institute of Mechanics of Chinese Academy of Sciences, vice president and dean of the Fifth Research Institute of the Ministry of National Defense, deputy director of the Seventh Machinery Department, deputy director of the Science and Technology Committee of the Commission of Science, Technology and Industry for National Defense, chairman of the third China Association for Science and Technology, vice chairman of the sixth to eighth CPPCC, and alternate member of the ninth to 12 Central Committee. He is currently a senior consultant of the Science and Technology Committee of the General Armament Department of China People's Liberation Army and honorary chairman of China Association for Science and Technology.
1956 put forward "opinions on establishing China's national defense aviation industry", and put forward an extremely important implementation plan for developing rocket and missile technology in China for the first time. Assist Nie in establishing the Fifth Research Institute of the Ministry of National Defense, which is a rocket and missile research institution. 1June, 1956, director of the institute. Since then, he has served as the technical director of the development of rockets, missiles and spacecraft in China for a long time, and has made outstanding contributions to the establishment and development of rockets, missiles and spacecraft in China with his rich knowledge in general, power, guidance, aerodynamics, structure, materials, computers, quality control and scientific and technological management. 1957 won the first prize of natural science of China Academy of Sciences, 1979 won the Outstanding Alumni Award of California Institute of Technology, and 1985 won the special prize of National Science and Technology Progress Award. 1989 was awarded the Rockville Medal and the title of world-class science and engineering celebrity, and 199 1 was awarded the honorary title of "National Outstanding Contribution Scientist" and the first-class English Model Medal by the State Council and the Central Military Commission.
