Study on the Information System of Tunnel stability in Arching Process of Surrounding Rock

摘要

It studied the early stability model of tunnels and establish the computer information system of early stability by using general software of ANSYS and Matlab in the paper. Firstly, the stress is displayed successfully through the model of stress intensity checking and algorithm. Then, it analyzed the influence of stress on surrounding rock in the arching process by using ANSYS software to calculate stress distribution in surrounding rock. Finally, it obtained the visualization display by using Matlab. Due to the limited conditions of computer, the numerical modeling process can not simulate the real situation of surrounding rock, we can only use approximate models to replace the whole rock system.
