大体积混凝土温度应力场的仿真分析

Mass Concrete Temperature Stress Field of Simulation Analysis

阐述了混凝土温度场和应力场的有限元仿真计算分析的基本原理,并基于上述理论,以ANSYS为平台,编制了混凝土三维非稳定温度场和应力场的仿真计算程序,同时通过大量算例验证了程序的正确性。

With mass concrete structures being widely used in engineering, their thermal stress continues to attract our attention. Its arch dam shape and working conditions make temperature control prominent. To acquire concrete arch of dam temperature creep and the distribution of stress field, we expounded the concrete temperature and stress field of finite element simulation of the basic principles , and based on the above theory, concrete three-dimensional steady-state temperature and stress fields are compiled in the simulation process.
