摘要
渗流是影响堆石坝安全运行的一个关键问题,由于水力学和地质条件的复杂性,堆石坝普遍存在渗流现象,随着时间的推移,渗流偏大可能导致渗流压力偏大、坝体结构不稳定、坝体沉降甚至失稳等.国内外对面板堆石坝渗流偏大相关案例的研究较少,对渗流偏大后相关的分析方法、处理的措施等均偏少,故以某电站混凝土面板堆石坝渗流偏大为例,通过对电站面板坝历史监测数据分析,采取的治理措施等进行剖析.
Abstract
Seepage is a key issue affecting the safe operation of rockfill dams.Due to the complexity of hydraulic and geological conditions,there is a common phenomenon of seepage in rockfill dams.Over time,excessive seepage may lead to increased seepage pressure,unstable dam structure,dam settlement,and even instability.There is relatively little research on cases of excessive seepage in panel rockfill dams both domestically and internationally,and there is a lack of analysis methods and treatment measures related to excessive seepage.Therefore,taking the example of concrete faced rockfill dam with excessive seepage in a power station,this paper analyzes the historical monitoring data of the power plant faced rockfill dam and the measures taken for governance.
