A Temperature and Stress Simulation of Immersed Tunnel during Precasting
摘要
Abstract
Started with the precast construction process of a segment of immersed tunel, temperature and stress varying of the tube were simulated. In the numerical model, the material parameters, thermal parameters and mechanical parameters were obtained through experiment. Moreover, complex thermal boundary and mechanical boundary conditions were considered. Finally, the numerical model was used to conduct a finite element analysis, and the evolution rules of temperature and stress field were obtained.关键词
