高速公路的排水设计显著影响着高速公路路基的稳定性及路面的使用寿命。水沟排水是高速公路排水系统的重要组成部分,在当前和今后的公路建设中,越来越高的生态环保要求,促使我们不仅要满足自身排水的需要,还要兼路域内生态恢复与环境保护。本文在阐述水沟生态排水重要性的基础上,分别归纳边沟、排水沟和截水沟等3类典型的排水技术在我国的研究和应用情况,剖析传统排水技术在应用中存在的主要问题,探讨分析相应生态排水技术的主要特征及型式,指出生态排水技术将是我国高速公路排水的发展方向,并展望了未来我国生态排水技术的研究及推广路径。
Drainage design of expressway significantly affects the stability of highway subgrade and the service life of pavement. Drainage drainage is an important part of expressway drainage system. In the current and future highway construction, higher and higher requirements for ecological protection have prompted us not only to meet their own drainage needs, but also to reconcile the ecological restoration with the environment protection. Based on the importance of ecological drainage of ditches, this paper summarizes the research and application of three typical drainage technologies such as ditches, drains and ditches in China, and analyzes the main problems in the application of traditional drainage technology , Discussed and analyzed the main characteristics and types of corresponding ecological drainage technology, pointed out that ecological drainage technology will be the development direction of expressway drainage in our country, and looked forward to the future research and promotion of ecological drainage technology in China.
