通过地质分析及数值模拟分析,研究青川县一个下部具有软弱基座、上部为硬质岩体的大型逆向层状岩质斜坡的变形破坏。得出其演化的地质力学模式为压致蠕变、拉裂、倾倒型。即软弱基座的压缩蠕变引起上部硬质岩体拉裂和弯曲,最终导致斜坡后缘拉张开裂而前缘压缩弯曲的倾倒式变形。 Through geological analysis and numerical simulation analysis, the deformation and failure of a large reverse stratigraphic rock slope with a weak base in the lower part of Qingchuan County and a hard rock mass in the upper part are studied. Obtained its evolution geomechanical model for the pressure-induced creep, cracking, dumping type. That is, the compressive creep of the weak base causes the upper hard rock body to crack and bend, which eventually leads to the dumping deformation of the slope leading edge and the compression and bending of the leading edge.
