The Analysis of Excavation Effect on Flexible Pressure Pipes Deformation Based on FLAC3D

摘要：

　　Based on the flexible pressure pipe structure calculation theory,by using the FLAC3D finite difference software,this paper analyzed the stress state of the flexible pipe and the rule of the pipe-soil interaction.Through orthogonal test method,the different parameter settings are named,such as the buried depth,excavation depth,excavation distance,the paper quantitatively studied the significance level of various factors which have effects on the pipeline excavation deformation.All the research will offer a scientific basis for the design and research of the follow-up flexible pipe.
