公路工程路基路面排水的重要性分析

Analysis on Importance of Drainage for Roadbed and Pavement of Highway Engineering

公路工程质量与使用寿命受到施工和外在环境因素的共同影响,其中,雨水冲刷或含水量高易造成路基不均匀沉降,路基塌陷及路面裂缝等多种病害.因此,建立健全公路工程的路基路面排水系统十分必要.论文分析了路基路面排水对于整个公路工程的重要性,总结了路基路面排水设计与施工的相关原则,并提出了具体的排水建设措施.

The quality and the service life of highway engineering are affected by the common construction and external environmental factors, among them, the rain wash or high water content will easy cause roadbed uneven settlement, roadbed subsidence and cracks and other diseases. Therefore, it is necessary to establish and improve the drainage system of road surface and roadbed of highway engineering. This paper analyzes the importance of subgrade and pavement drainage for the whole highway project, summarizes the relevant principles of subgrade and pavement drainage design and construction, and puts forward concrete drainage construction measures.
