Abstract:: On the basis of typical metro shield tunneling engineering, this paper studies stability and safety of rain and sewage pipeline. With the application of combine method of model test and numerical simulation, the deformation of pipeline and distribution of stress which is induced by the tunnel excavation are analyzed. As shown by calculation: (1) The uniform distribution can be presented in the settlement curve of pipeline when the pipeline and tunnel is parallel. When l/D is 1.5, the supervision points will be laid out densely and supervised frequently at the range of 1.5D between tunnel face and tunnel end. (2) The protective measures of tension and compression should be taken on the top and bottom of pipeline respectively.
