浅谈公路隧道排水设计与隧道路基病害防治

隧道排水设计是隧道正常运营的重要保障之一,排水设计的缺陷将导致路面积水、路面损坏、拱底冒水、翻浆冒泥等病害。本文通过研究沿江公路九座单洞双车道隧道的四种排水设计对比优劣,优化排水设计。并讨论了优化设计的适用情况。推荐一种施工质量容易控制且后期养护方便的隧道排水设计,供隧道设计人员参考或批评指正。

Remark on the Drainage Design of Highway Tunnel and the Prevention and Control of Roadbed Damage

Tunnel drainage design is one of the important guarantees for the normal operation of tunnels.Defects in drainage design will lead to road surface gathered water,road damage,water at the bottom of the arch,muddy mud and other damages.This paper optimizes the drainage design by studying and comparing the advantages and disadvantages of the four drainage designs of the nine-seat single-lane two-lane tunnel along the Yanjiang Highway.It also discusses the application of optimized design.It is recommended that a tunnel drainage design with easy construction quality and convenient maintenance in the later stage should be used by the tunnel designer for reference or criticism.
