在刘家峡水电站水库运用期间,发现左岸绕坝渗流加剧,加以该处断裂发育,并有顺层间倾向下游偏向河床的挤压破碎带存在,因而提出了进一步研究边坡稳定的问题。为了论证该电站左坝肩岩质边坡稳定问题,由水利水电科学研究院、水利电力部西北勘测设计院、北京大学等单位组成专题研究 During the operation of the reservoir of Liujiaxia Hydropower Station, it is found that the seepage around the left bank is aggravated, where the fault is developed, and there is the crushing zone where the downstream of the bedding layer tends to be inclined to the riverbed. Therefore, further studies on slope stability are proposed. In order to demonstrate the stability of the rocky slope at the left abutment of the power station, a special study was made by units of Water Resources and Hydropower Research Institute, Northwest Survey and Design Institute of Water Resources and Electric Power Ministry, Peking University
