黄土丘陵区市政道路排水工程设计优化

On design optimization of drainage projects of municipal roads in loess hill regions

以太原市王家峰市政道路排水工程为例,针对该项目兼具大坡度与湿陷性黄土的特点,从纵坡段雨水收集效果改善和湿陷性场地雨水入渗控制两方面,探讨了道路排水的优化设计方案,为道路的安全运营提供了保障。

Taking the drainage project of Wangjiafeng municipal road in Taiyuan as the example, the paper analyzes the features of the loess of the program with big slopes and collapsible loess, and explores the optimal design scheme of the road drainage from the improvement of the rain-water collection of longitudinal slopes and rainwater leakage control of collapsible sites, so as to provide some guarantee for the safety operation of the roads.
