Abstract: Seepage safety plays an extremely important role in the overall safety of reservoir dams. The causes of dam leakage are complicated and the consequences are serious which directly threaten the operation safety of the reservoir. This paper analyzes the causes for leakage at Cetian gravity dam and the left earth dam abutment, in aspects such as geology, structure, earthquake, seepage and deformation, for reference.

Key words: Cetian resrvoir, gravity dam, earth dam, leakage reason

摘要： 渗流安全在水库大坝的整体安全中占有极其重要的地位，土石坝渗漏成因复杂、后果严重，直接威胁水库的运行安全。笔者从地质、结构、地震、渗流、变形等方面对水库重力坝与左侧土坝坝肩段的渗漏原因进行了分析。
