某水利枢纽近坝库岸滑坡体稳定分析及评价

Landslide Stability Analysis and Evaluation of Reservoir Bank near the Dam in a Water Conservancy Project

在对某水利枢纽近坝右岸滑坡体特征及成因机理分析中,根据其可研、初设及施工各阶段的稳定性复核,施工中采取了减载方量和范围较小的削坡处理。由于削坡集中于滑坡体中部,对上部滑体的稳定有不利影响,经对削坡后滑坡体各断面在相应工况下的稳定性复核表明,整体边坡是稳定的,但安全富裕度不大,建议增设必要的安全监测设施,加强巡视检查,以便发现问题及时处理。

In the treatment of the right reservoir bank landslide near the dam in a water conservancy project,load reduction and slope cutting measures are adopted.However,as the slope cutting is majorly carried out in the middle part of the landslide,it may impose adverse effect on the stability of upper part.The stability of typical sections of the landslide after the slope cutting under different working conditions is re-checked.The results show that the landslide slope is generally stable but with small safety margins.It is suggested to add necessary safety monitoring facilities and strengthen the patrol inspection,so as to find and treat possible problems in time.
