Based on ANASYS Immersed Tube Tunnel Three-Dimensional Finite Element Analysis

Combining with the Pearl river underwater tunnel engineering project example from Huangsha to Fangcun in Guangzhou, this paper introduces the 3-dimensional finite element analysis ANASYS of immersed tube tunnel. According the data extracted from the actual project, immersed tube tunnel surrounding medium were studied and mechanical analysis of the interaction and its basic theory calculations. Then, calculate the results, through the establishment of model constraints division, loads and boundary conditions imposed on the grid and the immersed tube tunnel numerical simulation obtained the reasonably accurate analysis results. According to the figure of stress and strain, people can see the display of it easily .It is convenient for the design of the tube tunnels.
