摘　　要：以某座因未按设计要求施工而引起水库工程渗流和结构问题的土石坝为例,在工程现场检查和地质勘察的基础上,进行了大坝渗流安全分析、结构稳定分析、抗震安全分析,并对该水库工程的安全现状进行了综合分析与评价。分析结果表明:由于该工程未按设计要求进行施工,直接导致该工程结构不完整,大坝的渗透安全性、结构安全性及抗震安全性均不满足要求,大坝安全监测等工程管理设施欠缺,可归为三类坝。This work presents a typical case of small-sized reservoir with seepage and structural problems caused by non-standard and not following design construction. Based on field examination and geological survey, dam seepage safety, structural stability and anti-seismic ability are analyzed. The current safety status of the project is evaluated comprehensively. The result shows： non-standard and not following design construction directly caused strict dam safety problems, such as incomplete structure of the project, unsatisfied seepage, structural and seismic safety, lack of dam safety monitoring devices etc. Hence, the project here analyzed could be classified as ‘C＇.
