浇筑间隔时间对碾压混凝土重力坝影响分析

Finite element analysis on influence of pouring interval time on RCC gravity dam

为研究浇筑时间对碾压混凝土重力坝影响,以有限元软件ANSYS为基础建立有限元模型,分别从基础垫层、强约束区、弱约束区、非约束区几个不同的位置进行研究,得出浇筑间隔时间对坝体的温度变化和应力分布变化规律的影响,为实际工程提供理论依据。

In order to study the influence on pouring interval time on RCC gravity dam,the finite element model was established based on finite element software ANSYS.The research was carried out from several different positions of foundation cushion,strong constraint zone,weak constraint zone and unconstrained zone.The influence of the interval between the pouring and pouring on the temperature change and stress distribution of the dam provides a theoretical basis for the actual project.
