Simulation Analysis on Impacts on Existing Highway from Pipeline Underpassing Based on ANSYS
Pipeline construction underneath existing highway leads to settlement deformation of the existing highway thus bringing potential security risks to highway quality and traffic safety.Taking pipeline underpassing of G93 Highway as the research object,this thesis utilizes ANSYS Finite Element Simulation Software and Mol-coulomb Criterion to establish model and realizes burial depth simulation through equivalent gravity field.Results show that vertical displacement of earthing on the top of burial depth pipeline mainly appears as vertical settlement,whose maximum value reaches 15.3mm.The maximum shearing stress value of subgrade soil is 0.051MPa.Shearing stress of materials is within the range of shearing strength.Pipeline structure right below the highway is secure.
