摘要
通过对高速公路中央分隔带内部积水原因及其对路基和通信管道造成损害等问题的分析简述,提出了封闭中央分隔带并在土路肩下埋设通信管道的设计思想,并对两种埋设方式进行了经济对比分析,以供同类工程设计参考。
The causes of interior accumulation of water in the central reserveon speedway are described as well as this damage to roadbed and commtmi-ation pipe. A new design is advanced,occluding the central reserve and em-bedding communication pipe in the soil shoulder. Besides, this paper analyzeseconomic performance between the common way and the improved way. It may be helpful to similar designs in practical engineering.
