@@A FLAC3D numerical model considering pipeline-soil-tunnel coupling is established to simulate the effects on the 3 m diameter cable pipeline induced by Shenzhen metro construction from Yitian to Xiangmihu interval. Analysis shows that the pipeline and ground displacement matches the Gaussian distribution after constructing the left tunneling, but it no longer matches the Gaussian distribution after the right tunneling. The existence of buried pipeline changes the distribution of the displacement induced by metro tunnel across it. The longitudinal mechanical force of the pipeline has been improved after the right tunneling construction.
