摘　　要：根据坡月水库工程的地质条件,对9个重力坝岸坡坝段在考虑不同剪切面情况下的侧向抗滑稳定系数进行计算分析。结果表明:在本工程中采用不同剪切面假定方法计算得到的抗滑稳定安全系数均能满足规范要求,但计算结果存在偏差。根据实际地质参数采用合适剪切面假定及计算方法,对重力坝岸坡坝段的侧向抗滑稳定计算是十分重要的。According to the geological conditions of Poyue Reservoir,the lateral anti-sliding stability coefficients of nine gravity dam blocks under different shear planes were calculated and analyzed.The results demonstrate the an⁃ti-sliding stability safety factors calculated by different shear plane assumption methods all meet the requirements of code,but there exit deviation between the calculation results.It is very important to calculate the lateral anti-slid⁃ing stability of the bank-side dam blocks of gravity dam by proper shear plane assumption and calculation method according to the actual geological parameters.
