| 摘 要： | 通过研究某库岸滑坡在库水位升降条件下的稳定性动态变化及其渗流场的分析,获得在不同速率的库水位上升和下降过程中的非稳定渗流场;将计算得到的孔隙水压力用于滑坡的极限平衡分析,以讨论库水位上升和下降对滑坡稳定性的影响。结果表明库水位上升时滑坡稳定性总体逐渐增大,而库水位下降时稳定性总体逐渐减小。对于该滑坡,库水位骤降对滑坡影...

| Abstract: | Based on the studying for the dynamic changes of stability of a certain reservoir landslide under the conditions of reservoir water level fluctuation,and through the analysis of the seepage field,the transient seepage fields during the reservoir water level raising and falling are acquired;then the calculated pore water pressure is used in the limit equilibrium analysis of the landslide,in order to discuss the effect of the reservoir water level fluctuation on the stability of the landslide.The results show... |
