摘要
基于弹性力学的有关理论和Mohr Coulomb破坏准则,对三峡库区缓倾角滑面滑坡裂隙水压力致滑问题进行了定量化研究,探讨了裂隙水压力致滑的判据和缓倾角滑面滑坡滑动时临界水深的计算方法,并分析了裂隙水压力致滑的机理和过程。对三峡库区缓倾角地层滑坡的防治设计具有一定的意义。
According to elastic mechanics theory and Mohr-Coulomb rule, this paper quantitatively studies fissure water pressure, which causes sliding of horizontal strata in the Three Gorges reservoir area. The criterion of fissure water pressure causing landslides is discussed, then calculation method of critical depth of water is put forward when landslides of low dip slope fail. Furthermore, Author discusses the mechanism and course that the fissure water pressure causes landslide sliding. All these research will be significant for the landslides controlling of horizontal stratum in the Three Gorges reservoir area.
