某水利工程岸边坡稳定性影响分析研究

Analysis and study on the influence of bank slope stability of water conservancy project

水位变化对将对库岸边坡的稳定性产生影响,为了提高水库的安全管理水平,通过BIM及FLAC3D软件对某水库边坡水位变化下边坡稳定分析。结果表明天然工况下,边坡处于稳定状态;暴雨工况下,边坡基本为稳定的,但可能出现局部垮塌,尤其是在其中部陡坎带和北侧的前缘;蓄水条件下,正常蓄水位以上坡体基本不受影响,坡体前缘在长期浸泡作用下,坡体内粉砂质泥岩对堆积体位移具有控制作用。

The change of water level will have an impact on the stability of the bank slope of the reservoir. In order to improve the safety management level of the reservoir, BIM and FLAC3 D software are used to analyze the slope stability under the change of water level of the slope of a reservoir. The results show that the slope is in a stable state under natural conditions. Under the condition of heavy rain, the slope is basically stable, but local collapse may occur, especially in the middle of the steep slope and the north front. Under the condition of water storage, the slope above the normal water level is basically not affected, and the silty mudstone in the slope has a controlling effect on the displacement of the accumulation body under the long-term soaking of the front edge of the slope.
