杭州市闲林水库大坝试运行期渗流监测资料分析

Observed data of seepage of Xianlin Reservoir dam in Hangzhou during trial operation

渗流监测设施的有效布置和监测数据的采集、分析,是混凝土面板堆石坝的安全评价工作的重点。通过对闲林水库大坝试运行期间监测资料的整理分析,总结了闲林水库坝基、坝址两岸等重点部位的渗流变化规律,重点分析了降雨等因素对测点水位的影响,综合监测数据表明坝基、坝址两岸防渗系统工作正常,闲林水库渗流监测设施的布置合理、有效。

The key point to the safety assessment of concrete face rockfill dams is the effective layout of seepage monitoring facilities and the collection and analysis of monitoring data. Through the analysis of the dam monitoring data collected during the trial operation of Xianlin Reservoir, the seepage variation laws of the dam foundation, dam and other key parts are summarized. The influences of rainfall and other factors on the water level at the measuring points are analyzed. The comprehensive monitoring data show that the dam foundation and dam seepage control system works well at both sides. The layout of the seepage monitoring facilities of Xianlin Reservoir is reasonable and effective.
