路面排水是公路工程中一项重要的内容，排水是否畅通直接关系到路面、路基的稳定和养护、管理的质量．本文根据理论计算及实际操作中的一些具体情况分析、论述了公路纵向排水沟内雨水井的设计及如何进行合理布设。
Pavement drainage is an important part of highway engineering. Whether the drainage is smooth or not is directly related to the quality of the stability and maintenance of pavement, subgrade and management. Based on some theoretical analysis and practical analysis, this paper discusses the design of rainwater wells in longitudinal drainage gully of highway and how to arrange it rationally.
