摘　　要：文章依托东至县某小型水库心墙坝为工程背景,从除险加固中大坝渗漏问题出发,根据现场调查并结合地勘数据进行渗流稳定分析计算。调查结果表明,大坝结构安全;水库坝体及坝基防渗体系不完善,大坝填筑土料局部不满足规范要求,存在渗漏通道,渗流安全不满足规范要求,属三类坝。需及时采取措施进行整治,从而保证水库的正常运行。Relying on the core wall dam of a small reservoir in Dongzhi County as the engineering background,this paper starts from the leakage problem of the dam in the process of risk removal and reinforcement,and conducts seepage stability analysis and calculation based on the site investigation and combined with the geological survey data.The results of the survey show that the dam structure is safe;The anti-seepage system of the reservoir dam body and the dam base is not perfect,the soil filled in the dam does not meet the requirements of the specification,there is a leakage channel,and the safety of seepage does not meet the requirements of the specification,which belongs to the three types of dams.Timely measures need to be taken to rectify the reservoir to ensure the normal operation of the reservoir.
