摘　　要：水库大坝的渗流稳定分析是水库除险加固中不可或缺的一个环节,其对水库的除险加固有着至关重要的指导作用,该文以深圳市某水库大坝为例,采用有限元软件Autobank对大坝的渗流及稳定性进行计算分析。结果显示:各工况下坝体最大渗透坡降均小于允许渗透坡降,坝后未出逸,坝体渗透稳定满足要求,影响渗流的因素主要有渗透系数和上游水位。各工况下坝体最小安全系数的值均大于规范规定最小安全系数,坝坡稳定满足规范要求,影响坝体抗滑稳定的最小安全系数值的因素主要有水位和地震。The seepage stability analysis of a reservoir dam is an indispensable link in the reinforcement of a reservoir,and it has a vital guiding role in the reinforcement of a reservoir.Taking a reservoir dam in Shenzhen City as an example,the finite element software Autobank was used to calculate and analyze the seepage and stability of the dam.The result show that the maximum seepage slope of the dam body is less than the allowable seepage slope under all working conditions,and the seepage stability of the dam body meets the requirements,and the main factors affecting the seepage are permeability coefficient and upstream water level.The minimum safety factor of the dam body is greater than the minimum safety factor specified in the code under all working conditions,and the dam slope stability meets the code requirements.The main factors affecting the minimum safety factor of the dam body are water level and earthquake.
