金鸡水库沥青混凝土心墙坝施工期监测分析

Monitoring and analysis on construction period of asphalt concrete core wall dam in Jinji Reservoir

本文对施工期大坝监测数据进行了梳理,采用图表法、特征值比对等定性分析方法,结合工程地质、环境、降雨及施工过程等因素,对大坝渗流、心墙挠度、心墙与混凝基座接缝变形和心墙温度等监测数据进行了详细分析。结果表明:大坝渗流和心墙温度变化正常,坝体、坝基防渗效果较好,心墙与过渡料及填筑料间能协调变形,大坝工作状态良好。

Dam monitoring contents during construction period are generalized in the paper.Chart method,characteristic value comparison and other qualitative analysis methods are adopted for analyzing and discussing dam seepage,core wall deflection,core wall and concrete base joint deformation,core wall temperature and other monitoring data by combining with the engineering geology,environment,rainfall,construction process and other factors.The analysis results show that dam seepage and core wall temperature change are normal.Dam and dam base anti-seepage effects are good.The core wall can coordinate with the transition material and filling material for deformation,and the dam is operated well.
