Abstract:In the construction of underground engineering, the author found the phenomenon of horizontal force failure. After the first national conference on rock mechanics (Changsha, 79) and the soft rock Excavation Conference (Jilin, 80), it was learned that other domestic industries were similar. Then by the former Soviet Academy of Sciences information! ] Introduction, the horizontal crustal stress is relatively common, and its value sometimes reaches several times to ten times of the cap gravity stress. Why it is greater than, there is no theoretical solution, but the harm is great. Since 1974, the author has traced the source of the horizontal force and discovered the principle of geodynamic synthesis in 1985, which was published in the journal Engineering Mechanics of the Ministry of Construction (Tsinghua) [2][3][4]. It has great guiding significance in the construction, because it is based on the earth movement and generated (mechanics) basic theory, covering a wide range, belongs to the new view, new concept. In view of everyone's interest, and for the "Three Gorges" and "nuclear power" construction to provide thinking. This is introduced in several parts.
