| 摘 要： | 对加铺沥青面层的水泥混凝土路面进行温度应力分析发现：应力吸收层并不是越厚越好,应力吸收层的厚度对层间剪应力和结构竖向位移影响较大,而对沥青层底拉应力的影响比较小;高模量的应力吸收层材料对结构竖向位移、层间剪应力和沥青层底拉应力均不利。

| Abstract: | Through the thermal stress analysis on cement concrete pavement with asphalt overlay,it is found that: the depth of stress absorbing layer is not the thicker,the better;the impact of the depth of stress absorbing layer on the interbedded shearing stress and vertical displacement is comparatively great,but it has little effect on tensile stress of asphalt overlay bottom;the high-module stress absorbing layer material is disadvantageous to vertical displacement,interbedded shearing stress and tensile stress o... |
