| Abstract: | With XueFeng mountain super-long high-way tunnel practice in HuNan province as an example,and according to the fact of the graduate releasing of geo-stress in the practical process of tunnel excavation,the paper made some development and numerical simulation research for the tunnel relying on virtual-supporting-force method.It finally acquired an easy and precise idea for understanding the tunnel stress-deformation field in surrounding rock of tunnel,which is conformed with the engineering practice and thus provide an idea and method for numerical simulation study during tunnel excavation. |
