Stress analysis of asphalt concrete pavement for continuous box girder bridge under interfacial contact condition
摘要
Abstract
An interlaminar contact model of deck pavement for a continuous box girder bridge was established and computed by ANSYS software.The effects of thickness and elastic modulus of deck pavement,cohesive force between layers and void area between layers on the stress of asphalt concrete pavement were analyzed.The results show that the thickness of upper layer of asphalt concrete is suitable from 4 cm to 6 cm,and the thickness of waterproof almost has slight effect on the stress of asphalt concrete layers.Increasing the elastic modulus of upper and lower layers of asphalt concrete can respectively increase the stresses,while increasing the elastic modulus of waterproof can decrease the stress of asphalt concrete layers.When the cohesive force between two neighbouring asphalt concrete layers is greater than 1.2 ×105 Pa,all kinds of stresses of asphalt concrete layers nearly remain unchanged.The relative position between void area and load region has great influence on the stresses of asphalt concrete layers.关键词
