摘　　要：以某土石坝工程为研究对象,根据该大坝地质勘察报告提供地质参数计算,选取典型断面进行渗流计算,确定各工况下的浸润线位置,并对计算结果进行分析,评价结构的安全状况,研究结果表明:大坝在各种工况下的渗透坡降均小于允许渗透坡降,大坝不存在渗透变形破坏。Take an earth-rock dam project as a research object, and according to the geological survey report about the dam geology parame- ters, typical cross-section of dam is selected to calculate the seepage, and then to determine saturation line of various operating conditions. Then the security situation of darn is analyzed. The results show that penetration gradient of the dam in a variety of operating conditions are less than the allow penetration of gradient and the dam is safe.
