四川某水电站新桥1#滑坡体成因及稳定性分析

新桥1^#滑坡体位于美姑河拟建某水电站库区中部左岸，由于方量大，所以该滑坡的稳定性对水库的安全运行有直接影响。根据野外实地调查及采样试验等数据，阐明其成因及特征，并采用有限元法对其做三维数值模拟分析其稳定性，对于水电站施工期及运行期采用何种方式支护或处理该滑坡具有实际意义。

Analysis on Genesis and Stability of Xinqiao 1# Landslide on Meigu River

Xinqiao 1^# landslide locates at left bank of the middle of the reservoir of Niuniuba hydroelectric station on Meigu River, owing to the huge volume, the stability of the landslide is very important to run the reservoir safety. Based on the data obtained by the field investigations and tests of core samples, the authors illuminated the genesis deeply, and made a three-dimensional numerical model byusing the method of finite element analysis, all these works have grate practicality significance to decide which method to choose to deal with the landslide during construction period or running period of the hydroelectric station.
