杜寨水库大坝渗流监测形态分析

Analysis of Seepage Monitoring in Duzhai Reservoir

通过智能化监测设备收集了杜寨水库的库水位过程线、大坝坝体和坝基的浸润线和水位情况,采用最小二乘法计算了各监测点与库水位之间的相关关系,对杜寨水库的渗流成因及其危害程度进行了分析判断,得到杜寨水库0+300断面范围内的渗流形态存在异常,推断在下一次汛期或强降雨期间该断面有可能产生强度较小的渗流现象。

The reservoir water level hydrograph,the infiltration line and water level of the dam body and dam foundation of the Duzhai Reservoir were collected through intelligent monitoring equipment,and the correlation between each monitoring point and the reservoir water level was calculated by the least square method.The cause of seepage in Duzhai Reservoir and its damage degree were analyzed and judged,and it was found that the seepage pattern in the section 0+300 of Duzhai Reservoir was abnormal.It is concluded that the seepage phenomenon with low intensity may occur at this section during the next flood season or heavy rainfall.
