摘　　要：库岸边坡对水库的安全运营影响巨大,一旦失稳会造成巨大的生命财产损失。以云南省兰坪县兔江桥左岸库岸边坡为研究对象,使用Geostudio软件进行地质建模,采用摩根斯坦法计算不同的水库蓄水量在不同工况下对兔江桥边坡稳定系数的影响。研究表明,现库水位和设计正常蓄水位在各工况下稳定系数均未达到抗滑稳定安全系数。建议及时疏散周围居民,延长监测周期、进行边坡加固,并注意暴雨对边坡的影响。The slope of the reservoir bank has a great impact on the safe operation of the reservoir,once the instability will cause huge loss of life and property.Taking the left bank slope of Tujiang Bridge in Lanping County,Yunnan Province as the research object,the geological modeling is carried out using Geostudio software,and the influence of different reservoir water storage capacity on the slope stability coefficient of Tujiang Bridge under different working conditions is calculated by Morgenstern-Price method.The study shows that the stability coefficient of the current reservoir water level and the designed normal storage water level does not reach the safety factor of anti-sliding stability under various working conditions.It is suggested that the surrounding residents should be evacuated in time,the monitoring period should be extended,the slope should be strengthened,and the influence of rainstorm on the slope should be paid attention to.
