【摘要】 宝平线沽源～赤城段是一条山区高等级公路,沿线雨量多而集中,因此,排水工程及水害防治是道路设计的重要内容,必须设置完善的排水系统才能确保路基的稳定和良好的路面使用性能。通过现场调查并结合试验研究提出的路基排水设施的系统设计方法和施工要点,经试验路观测结果证明,该方法可以有效地排除地下水,同时可为同类工程提供参考。更多还原

【Abstract】 The highway from Kuyuan to Chicheng section of Baoping line is a mountain high-level highway,and there are much more rain along it.So,drainage engineering and water damage prevention are the important contents for highway,we must design perfect drainage system to ensure roadbed’s stabilization and highway performance.Through investigation and experiment research,the key points and design method of drainage system was put forward,and the observation results on experiment of highway showed the method can effectively drainage under water which can also give reference for similar engineering.更多还原
