对山区公路排水设计的几点思考

An Analysis on the Design of the Highway Drainage in Mountain Area

介绍山区公路排水系统的组成、山区公路排水系统设计应遵循的原则以及山区公路排水设计现状等问题,并从测设前期工作、排水设施形式、水文水力计算等几个方面阐述山区公路排水设计时应考虑的设计要点。认为只有遵循这些要点,才能减少因排水问题造成山区公路的损毁,减少后期养护资金的投入。

The components of highway drainage system,the principles of highway drainage design and the reality of highway drainage design have been presented.The design essentials of highway drainage have been explored from three aspects,viz.preliminary work before measure and design,the form of drainage facilities and hydrology-hydraulics calculations.In order to reduce flood disasters and the fund for the latter maintenance,these design essentials must be followed when designing the highway in the mountain area.
