| Abstract: | In order to reduce the negative impact of the environment due to shallow tunnel construction,the ground movement and deformation are estimated through simulating the entire process of the shallow tunnel construction,and the surrounding rock stress and strain in different situations are obtained.On this basis,the non-linear regression method for consideration of time factors is used to obtain the space-time deformation law of ground surface.This work provides a new way of estimating the effect of shallow tun... |
