摘要
石砭峪水库大坝高85m,是国内最高的沥青混凝土面板堆石坝。本文叙述了石砭峪坝监测系统的设计准则;详述了观测项目的设置、测点的布置及仪器的类型数量;并对已取得的观测资料作了初步整理分析。资料分析的结果表明:大坝监测系统的设计是合理的,能较全面地反映大坝蓄水运行的工作性态。目前大坝坝体的沉降已渐趋稳定,周边缝的最大开度值为1.27mm,经过帷幕灌浆漏裂处理后,面板板后水位已显著下降,大坝运行状况已有所改善。
Shibianyu dam is the highest dam of all the goudron concrete face rockfill dams built in our country.Its height is 85m.In this paper, the design rules of observations, items of observations, points of observations and types and quantity of apparatus are dilated. The observation data are analyzed. Results of data analysis show that the design of the dam observation system is reasonable and the working behavior of the dam can be reflected. Now, the settlement of the dam is almost invariable. The opening of peripheral points is 1.27mm. After curtain grouting, the water level behind the face slab has obviously descended, and the working behavior of the dam has been improved.
