摘要
以山西省某水库工程为对象,在概述该水库运行现状及地质层土体物理力学特性的基础上,对大坝坝体坝基渗漏病害进行了勘测调查,基于此提出混凝土防渗墙加固技术,并从技术具体实施层面又提出坝顶修筑塑性混凝土防渗墙(方案一)和大坝上游坝坡底部修建塑性混凝土防渗墙(方案二)两种方案,最后采用方案一;对该方案下塑性混凝土防渗墙施工技术应用要点进行探讨,可为类似工程施工控制提供借鉴参考。
Taking a reservoir project in Shanxi Province as an object, on the basis of summarizing the operation status of the reservoir and the physical and mechanical properties of soil in geological layer, the seepage disease of the dam foundation is investigated. Based on this, the reinforcement technology of concrete cut-off wall is proposed. From the technical implementation level, two schemes of plastic concrete cut-off wall at the dam crest, which is scheme, and plastic concrete cut-off wall at the bottom of the upstream dam slope, which is scheme 2. Finally, scheme 1 is adopted. The application points of plastic concrete cut-off wall construction technology under this scheme are discussed, which can provide reference for of similar engineering construction control.
