上海市双流路病害分析与路面结构设计浅析

Damage Analysis and Pavement Structure Design of Shuangliu Road in Shanghai

对上海市双流路的病害以及交通情况进行了调研,分析了病害产生的原因。依据调研的交通状况采用BISAR软件对双流路原有结构路面以及新设计的路面结构进行了力学计算,对两种路面结构进行了对比分析。结果认为原有的路面结构的路表弯沉值与层底拉应力不满足设计容许值是引起路面病害的主要原因,并提出满足设计要求的路面结构设计方案。

The damage and traffic situation of Shuangliu road in Shanghai were investigated and the causes of the damage were analyzed. According to the traffic condition, the mechanical calculation of the old/new pavement structure was carried out by using BISAR software. And the two pavement structures are compared and analyzed. The results show that the pavement deflection and the tensile stress at the bottom of the pavement do not meet the allowable value of design, which are the main causes of pavement damage. The proposed pavement structure meets the design allowable value.
