Abstract

Taking Jianchuandong dangerous rockmass in Wushan for an example, based on analyzsis of geological conditions, displacement of base and stress monitoring data, we summarized the present deformation and stress state of the dangerous rockmass, then found that the strength of it remaining reduce. Meanwhile, using FLAC^2D we set up four simulation conditions, including Initial natural, Initial saturation, critical sliding and destabilizing to research the rule of rock base and shale strip limestone when facing up rock slide. The results show that decreasing of base strength of argillaceous limestone will make dangerous rockmass in a state of critical sliding. Stability analysis of the above also provides a basis for further control of the design.
- Three Gorges Reservoir,
- sub-horizontal thick-bedding slope,
- Jianchuandong dangerous rockmass,
- factor of safety
