摘要
Abstract
The temperature cracks of mass concrete closely relate to the temperature field and tempera-ture stress. The article focuses on the application of finite element method in solving the mass concrete temperature field and temperature stress. Taking Nanganghai Tunnel in Xiamen as an instance, a mass concrete temperature stress equation is proposed, a calculation program of mass concrete temperature field and temperature stress is also written. The finite calculation results show that the finite element soft-ware can simulate the stress development process of mass concrete under temperature field, the results ac-cord with the temperature stress distribution rule in the concrete pouring process.关键词
