石衡高速公路低路基设计应用研究

Research on Design Application of Low Subgrade of Shiheng Expressway

根据石衡高速公路取土困难现状,采用平原区低路基专项设计,针对地方道路交叉做合理排水设计,解决低路基通道排水困难问题,有利于降低造价。

In view of the difficult situation of soil sampling in Shiheng expressway,the special design of low subgrade in plain area is adopted,and the reasonable drainage design is made for local road intersection to solve the problem of drainage difficulty of low subgrade channel,which is conducive to reducing the cost.
