| Abstract: | In this paper,a 2 D visco elasto plastic FEM is used to analyze the stability of the excavation and lining structure of a nearby double tunnel in the national highway from Beijing to Zhuhai, in the area of Guangdong province. The stress deformation state and the evolvement status of the plastic and tension zones of the surrounding rock and the lining structure are analyzed and compared on the basis of calculations under five different conditions. |
