Buried Pipeline Optimization in Landslide Area
It is difficult to avoid the landslide for the buried pipeline in the West-East gas transmission project, because of the influence of topography, expense and so on. And the stability of landslide affects the pipeline of long-term security importantly. Based on the deformation analysis of a landslide, the pipeline stress was studied by using the FlAC3D under the landslide thrusting force. Changed the pipeline buried depth, position and dip between pipe axis and landslide sliding direction and established different combination by the Orthogonal Experiment. And the stress characteristics of pipeline were understood. According to the shear stress, the buried pipeline optimization scheme was proposed, that the depth was 4m, the position was 0m and the dip was 30 degree. That has some values for the pipeline construction in landslide area.
