3D numerical analysis of Underground Culvert constructions on neighboring existing pile

Underground Culvert construction always adjacent to existing pile foundation, it is an important problem how to ensure the security of the existing pile. Taking the Underground Culvert at West Ring Road of the South-North Water Transfer Project as an example, the 3D numerical simulation had been carried out and the stress deformation Law and the stability of the pile was studied. The results had shown that the Underground Culvert construction had little impact on the stress and the deformation of the pie, and working period does not endanger the viaduct´s safety theoretically. The conclusions and suggestions are valuable for the engineering design and worth as references for the similar projects.
