摘要
通过交通量及交通组成调查 ,利用HPS便携式轮重仪进行现场轴重测试 ,得到车辆的轴载谱及超载的可靠数据。从重载交通的标准轴载换算和累计当量作用次数入手 ,得出超载是水泥混凝土路面结构早期破坏的重要原因之一。提出路面结构设计应充分考虑超载运输影响及针对重载交通的公路技术。
The distribution of actual axle load and data of overload were obtained through traffic surveys and tests with the HPS portable wheel load scale. By means of conversion to standard axle load and calculation of accumulated applications of the equivalent axle load, it could be concluded that overloading is one of the most important reasons for the premature failure of cement concrete pavement structures. It is proposed that the influence of overloaded vehicles should be emphasized in pavement structure design, along with suggestions of highway technology, automobile technology, and administration for heavy load highways.
