水害防治一直是山区高速公路路基设计的重要内容,山区高速公路路基的稳定性及路面的使用寿命与排水设计的合理与否有直接联系,因此,必须完善排水系统确保路基路面的稳定和良好的使用性能,降低和防止路基水毁灾害的发生。本文以巫(巫山)奉(奉节)高速公路为例,介绍了山区高速公路路基路面排水设施的系统设计和施工要点。同时,作为一个实用工程,本文中的一些方法和思想能为同类工程提供参考。
Water damage prevention and control has always been an important part of highway subgrade design in mountainous area. The stability of highway subgrade and the service life of pavement are directly related to the reasonableness of drainage design. Therefore, it is necessary to improve the drainage system to ensure the stability and good Use performance to reduce and prevent the occurrence of water-damaged subgrade hazards. Taking Wu (Wushan) Bong (Fengjie) Expressway as an example, this paper introduces the system design and construction essentials of subgrade drainage facilities in mountainous expressway. At the same time, as a practical project, some of the methods and ideas in this article can provide reference for similar projects.
