摘要
针对碾压混凝土拱坝薄层碾压的结构特点以及坝体埋有一定数量温度计的情况,引入渗流场与应力场耦合的数学模型分析水压对坝体位移的影响,采用"开关函数"解决坝体温度位移时空分布问题,探讨了建立碾压混凝土拱坝位移监控模型的方法,并给出了工程应用实例.
<Abstrcat> According to the structure characteristics of thin roller compacted layer of roller compacted concrete arch dams and the feathers of thermometers buried in dam body,the method of setting up the displacement monitoring model of roller compacted arch dams is discussed,by using the mathematical model of coupling between stress field and seepage field to analyze the influence of dam displacement on water pressure and using switch function to analyze the dam body temperature displace distribution.Thismethod is applied in Shapai roller compacted concrete arch dam.
