摘要
铜场水库大坝为黏土心墙堆石坝,2010年7月15日填筑至设计高程,该工程2011年12月10日下闸蓄水。文章通过对初期蓄水监测资料的分析,初步揭示了铜场水库大坝在上游水位的作用下,坝体渗透水位上升的原因。监测成果表明:①初期蓄水对大坝沉降影响不大;②0+090 m与0+145 m断面的倾度为0.01%~0.07%之间,说明心墙沉降比较均匀;③坝体渗流监测点的渗透水位随上游库水位的变化而变化。
The dam of Tongchang reservoir is of the rockfill dam with clay core.It was filled to the designed elevation on July 15, 2010.The reservoir impounded on Dec.10, 2011.Through the analysis on the monitoring data of the initial impoundment, reasons for the rising of the seepage level of the dam body under the action of the upstream water level are initially revealed.The monitoring results show that ①the initial impoundment rarely impacts the dam settlement; ② the inclination of surfaces at 0+090 m and 0+145 m is 0.01% ~0.07%.This presents that the core settlement is even;③the seepage level at the monitoring points of the dam body varies with the reservoir level.
