Abstract

The principle of shear band propagation method (SBP) and its application in the stability analysis of submarine landslides were briefly introduced. Then, Limit equilibrium method（LEM）and the SBP based on the Gauss formula were used to analyze the stability of a typical submarine slope in Liuheng island, Zhoushan, China. Finally, parametric studies were carried out to investigate the effects of input parameters of the SBP on the shear band propagation coefficient R. Results show that when R no more than 1, the failure length of the slope shear zone obtained by the LEM is the same as that of the SBP. However, when R more than 1, the failure length of the slope shear zone calculated by the SBP is larger than that calculated by the LEM. Besides, it can be seen that the factor of safety calculated by the SBP is lower than that of the LEM in the failure zone of the slope. It is found that both the seismic factors and characteristic displacement have a great influence on R values.

基于剪切带扩展法的海底斜坡稳定性分析

简介剪切带扩展法（SBP）的原理及其在海底滑坡稳定性分析的应用；以舟山六横岛典型海底斜坡为分析案例，开展基于高斯函数的SBP和极限平衡法（LEM）斜坡稳定性对比分析研究；进行SBP输入参数对剪切带扩展系数R的敏感度分析. 研究结果显示，对于斜坡剪切带破坏长度，当剪切带扩展系数R不大于1时，LEM与SBP得到的滑坡滑裂面区域一致，当R大于1时，SBP计算得到的最终滑动区域比LEM计算得到的区域大；在斜坡发生滑动破坏区域SBP比LEM计算得到的安全系数低；地震影响因素和土体特征位移对R的影响较大.
