Simulation Analysis on Impacts on Existing Pipeline Displacement from High-fill Slope Construction Based on ANSYS
During construction process of high-fill slope,additional load of foundation gradually increases with the increasing of filling height,whose influences on existing underground pipeline displacement has to be pay attention.This thesis takes existing oil pipeline as research object,in which upper filling brings about surrounding soil displacement,thus posing great threat to normal use of pipelines.Through analyzing on surroundings of pipelines and filling construction of slope,this thesis utilizes ANSYS Finite Element Simulation Software to construct model and realizes burial depth simulation through equivalent gravity field.Results show that vertical displacement of left pipeline mainly focuses on both sides,which explains that influences of filling on left oil pipeline mostly exist on both sides.The maximum vertical displacement is 19.0mm.Horizontal displacement mainly concentrates on top and bottom with the maximum value 5.7mm.Vertical displacement of right pipeline also centers on both sides,which explains that influences of filling on right oil pipeline mostly exist on both sides.Its maximum vertical displacement is 18.6mm.Horizontal displacement mainly concentrates on top and bottom with the maximum value 3.1mm.
