| 摘 要： | 针对雅砻江楞古水电站边坡稳定性问题,以马河崩塌体边坡为例,选取岩体重度、粘聚力、内摩擦角、水位、地震系数为影响因子,以边坡的安全系数为指标,基于均匀设计开展数值试验,对试验结果进行灰关联分析,得出各因素与边坡安全系数之间的关联系数和关联度。研究结果表明,各因素对边坡稳定性的影响大小依次为内摩擦角水位地震系数粘聚力重度。

| Abstract: | Lenggu hydropower station is located in alpine valley region of Yalong River. Due to the complex geological environment, the stability problem is sever and it is influenced by numerous factors. With slope safety factor chosen to be the index, the unit weight, cohesion, internal friction angle, water level and seismic coefficient were selected to be the factors. Then, the numerical experiments based on uniform design were done and the results were analyzed with grey correlation theory. The result show that the sequence of magnitude of correlation with slope stability is:internal friction angle > water level > seismic coefficient > cohesion > unit weight. |
