摘要
针对碾压混凝土坝薄层碾压的结构特点,引入渗流场与应力场耦合的数学模型分析坝体在水荷载、温度荷载等作用下引起的弹性位移分量,采用粘弹性有限元计算坝体在水荷载等作用下引起的时效位移分量,讨论碾压混凝土坝变形一级监控指标的拟定方法,并应用于实际工程.
According to the structure characteristics of RCC dam,the method is discussed of calculating RCC dam's primary deformation monitoring indexes,by using the mathematical model of coupling between seepage field and stress field to calculate elastic displacement component of dam body under water and tomperature loading,and visco-elastic finite element method to calculate time displacement component of dam body under water and other loading. The method is applied in Shapai RCC arch dam.
