摘要:
为了研究设置应力吸收层后旧水泥混凝土沥青加铺路面结构的力学响应,采用有限元分析方法,建立水泥混凝土加铺路面接缝在最不利温度时的温度-荷载耦合模型,对不同沥青加铺层厚度、模量和不同应力吸收层厚度、模量工况下的温度应力与温度-荷载耦合应力进行研究.根据计算结果,提出了沥青加铺层、应力吸收层的合理厚度范围,并对加铺层与吸收层的模量加以控制
Abstract:
In order to study the mechanic response of asphalt overlay structure which was set with stress absorption layer, the finite element methods were adopted to build a thermal-loading coupled model at the position of juncture on overlay cement concrete pavement under the most adverse temperature. Research is carried out on the thermal stress and the thermal-loading coupled stress under the condition of different modules and thicknesses of asphalt overlay and stress absorption layer. According to the study, a reasonable thickness range of asphalt overlay and stress absorption layer was presented. At the same time, the modules of asphalt overlay and stress absorption layer should be controlled properly
