层状岩体边坡变形破坏模式及滑坡稳定性数值分析

FAILURE PATTERN AND NUMERICAL SIMULATION OF LANDSLIDE STABILITY OF STRATIFIED ROCK

论述了层状岩体的地质特征及其物理力学特征 ,在此基础上 ,归纳了层状岩体构成的边坡几种变形破坏模式 ,然后对边坡破坏后形成的滑坡进行了稳定性数值分析。最后得出一些结论及认识。

The geologic characteristic and physico mechanical properties of stratified rock are studied. It is shown that the shear fracture and tension fracture are the major deformation damage patterns of the stratified rock. The shear strengths of structural plane and rock are the major property of this kind of rock. Deformation damage patterns of the slope constituted by stratified rock are classified into four types. In addition, the stability of landslide developed on these slopes is simulated by numerical method. It is important problem how to choose a reasonable failure criterion in the analysis of slope stability.
