Abstract

A curved box girder bridge was simulated by ANSYS software, and the interlaminar contact form of deck pavement was achieved by the contact element and target element. Stresses of the asphalt concrete pavement were calculated and gained when material parameters were changed and interlaminar disengaging area was changed. The results showed that: when the thickness of the upper layer of asphalt concrete increased, the most stresses of the asphalt concrete all decreased, and reasonable thickness of asphalt concrete was gained; when the elastic module of the waterproof increased, the most stresses of the asphalt concrete all decreased, so waterproof of high elastic modulus was suggested to be used in practical engineering; when disengaging area occurred between two adjacent layers and vehicle load located on the layer, the stresses of the asphalt concrete all increased; the size and position of disengaging area had great influence on the stresses of asphalt concrete.
