摘要
渗流状态是评价和监控土坝安全的重要依据,渗流监控指标对于保障土坝安全具有重要意义。以深圳水库主坝MXG监测断面为工程实例,以土坝坝体渗压、浸润线和渗透坡降为研究对象,从不同的角度对土坝坝体渗流监控指标的拟定方法进行了研究,为同类土坝渗流监控指标拟定提供了较好的参考。
The seepage state in an embankment dam is of great importance for the monitoring and evaluation of its safety. While different seepage monitoring indicators are available, which should be chosen carefully. A case study on the MXG monitoring section of the main dam of Shenzhen Reservoir is presented. Three monitoring indicators, i.e. the dam seepage pressure, phreatic line and seepage gradient, are studied. Determination method for the seepage monitoring indicators is discussed from different perspectives. It could be a useful reference for similar embankment dams in the determination of seepage monitoring indicators.
