| Abstract: | With the rapid development of traffic infrastructure construction ,double sidewall drift construction is widely used in large-span deflective pressure tunnel to control the soft surrounding rock deformation. Combined with engineering practice, this paper analyses the relation of construction process and initial support deformation of deflective pressure tunnel,which could be refered to the same projects. |
