Simulation Analysis for Temperature Field of Yabiluo RCC Gravity Dam

Liu Xin-gang

Abstract

One of the principal problems in construction of a RCC dam is the temperature control and crack prevention.In this paper the temperature field simulation analysis of Yabiluo RCC gravity dam is done with 3D FEM.The factors such as change of adiabatic temperature rise with age of concrete,water pipe cooling, placing concrete in layers and change of environmental temperature are considered in the analysis.The laws of temperature field distribution of Yabiluo RCC gravity dam and its change with time have been obtained.
