The Mechanics Properties Analysis Of Pavement Structure Caused By The Urban Parallel Underground Pipeline

Along with the development of the social productive forces and people’s materialculture raise，also with the rapid development of urban construction, that people’srequirements are constantly improved, and the influence of the pavement pipeline structureunderground cannot be ignored, By existing roads investigation, we can found thatunderground parallel pipelines are more representative in underground pipeline engineering,it has the actual research significance. Based on the finite element theory, use theapplication of the finite element analysis software ANSYS, The mechanics properties finiteanalysis of pavement structure caused by the Urban parallel underground pipeline.According to the structure, road boundary constraint conditions and load conditions, build areasonable finite element model. In order to study the influence of the pavement structurewe change the pipeline buried depth、the backfill soil modulus of groove and the spacebetween pipeline. By analysis the model data, it shows that due to the existence ofunderground parallel pipeline, the way of the local stiffness structures are changed,differential settlement occurs on the surface of asphalt concrete, under the influence ofvehicle load, there are certain rules when Parallel pipeline with different buried depth、backfill soil modulus of groove and the space between pipeline. We through the finiteelement to analysis the asphalt concrete pavement which contain the parallel pipe, we hopeto provide certain reference for asphalt concrete pavement city road design and constructionwhich include parallel pipeline. And in the light of the damage characteristics of thepavement with parallel pipeline underground the structure, then puts forward thereinforcement technique measures.
