沥青路面温缩裂缝的应力强度分析

Thermal Stress Intensity Factor Analysis for Aspphalt Concrete Pavement

本文以二维弹性层状体系理论为基础，求得了半刚性基层沥青路面结构中沥青面层产生低温收缩裂缝尖端应力强度因子的积分表达式，并对裂缝尖端的应力强度及其与路面温度分布和路面材料特性参数的关系进行了数值分析。

In this paper,based on thermoelasticity of two-dimension layered pavement structure,a method of calculating the thermal stress intensity factor of the thermal contracted fracture in a asphalt concrete pavement on semi-rigid base.is proposed, and numerical analysis and mechanics analysis are made to clarify the laws of thermal stress intensity factor variation due to characteristic of pavement material and pavement temperature fields.
