3D Finite Element Analysis Of Asphalt Pavement With Crack

This text makes the simple introduction to calculating and basic development in mechanics of asphalt road general situation at home and abroad, flexible layer system theories and finite element methods first, expatiating the research purpose and meanings.Based on the results of existing studies, choose two typical structures of pavement and subgrade, analyzed by using the pavement engineering finite-element method in conjunction with ANSYS software.Then uses the different asphalt road parameters: the waterproof membrane modulus, the pavement modulus and the pavement thickness, receive the different asphalt road responds: the pavement deflections, the pavement press stresses, the pavement underside stresses, the waterproof underside stresses, the pavement shearing stresses and the waterproof shearing stresses.Compared with asphalt pavement structure around dehiscence mechanics response. Analysis pavement with crack position, length and depth to structure influence.Inverstigating dynamic response of asphalt pavement structure under moving loading, analyzing the pavement deflections and the stress characteristics of pavement under moving loading.
