李四光和地质力学
Li Siguang and Geomechanics
20世纪20年代，地质学家，中圈地质力学的奠基人李四光建立了新的边缘学科“地质力学”，为地质学理论作出了伟大贡献。倡导用力学观点研究地质，建立了 “构造体系”概念——地质力学最基本的概念之.为探索矿产分布的规律及其研究地壳运动提供r新方法。他的理论为中困石油的探索和发现作出了重要贡献。
In the 1920s, Li Siguang, a geologist and founder of geological mechanics of China, set up the subject of geological mechanics and made great contribution to the geological theory. He studied lithosphere with the mechanic theory, and established the tectonic system, one of the bask concepts of tectonic mechanics. He provided new ways to explore the natural phenomena and ushered in new ways of studying the lithosphere movement. His theory made great contribution to China's oil reconnaissance and survey.
