基于有限元分析的沥青路面坑槽修补动态响应及界面破坏机理研究
Research on dynamic response and interface failure mechanism of asphalt pavement pit repair based on finite element analysis
摘要
Abstract
To address the problems of short service life of asphalt pavement pothole repairs and the high incidence of secondary distresses such as differential settlement,shoving,and upheaval,the premature failure mechanisms of pothole repair structures were investigated.Based on ABAQUS software to simulate the actual stress state after pothole repair,a variety of working conditions were set up to explore the mechanical response law of pothole repair structure under vehicle load and temperature load.The results show that when the modulus of the patching material is similar to or slightly higher than that of the original pavement,the stress and deformation of the joints can be effectively controlled.With the increase of the friction coefficient φ,the normal and shear stresses of the joints increase significantly.When φ reaches 0.6,the risk of damage of the patches increases significantly.Meanwhile,an increase in axial load leads to a linear increase in pit interface stress,and for every 0.1 MPa increase in load,the compressive and shear stresses increase by 12.5%and 15.0%,respectively.The disturbance at the bottom of the trench further exacerbates the joint stresses and increases the risk of secondary distresses such as settlement and pushover congestion.However,the increase of interfacial friction coefficient can effectively reduce the stresses in the repaired joints,and when the interfacial friction coefficient is increased from 0.2 to 0.9,the normal stress and shear stresses in the Y and Z directions at the transverse bottom joint of the pothole decrease by 19.3%,13.6%,and 17.3%,respectively.关键词
