摘　　要：以纳雍县得勒科水库左岸边坡为研究对象,采用M-P法、Janbu法等对水库左岸开挖边坡的整体稳定性进行分析计算。结果表明,左岸开挖边坡处于稳定状态,开挖边坡仅作常规处理即可。目前水库大坝已封顶,在边坡开挖及坝体填筑过程中均未出现边坡失稳现象,理论计算与施工后的实际情况相符,可为边坡稳定性评价提供理论支撑。Taking the left bank slope of Deleke Reservoir in Nayong County as the research object,the overall stability of the excavation slope on the left bank of the reservoir was analyzed and calculated using M-P method,Janbu method,etc.The results showed that the excavation slope on the left bank was in a stable state,and only conventional treatment was needed for the excavation slope.At present,the reservoir dam has been capped,and there has been no slope instability phenomenon during slope excavation and dam filling.Theoretical calculations are consistent with the actual situation after construction,which can provide theoretical support for slope stability evaluation.
