  公路隧道平面选线,要服从路线总体走向。虽在路线可调整范围内,宜选择地质条件好的位置,但特长隧道地质条件都较复杂。尤其是湿陷性黄土,软弱泥岩,糜棱岩,角砾岩等破碎带围岩地段,隧道开挖施工时,大都会遇到渗水,涌水等情况。吸取近年来对隧道的施工经验和科研成果,总结出排水半圆管,纵横向排水管,中心排水沟,土工布和防水板的安装技术,以及提高二衬防渗性能,隧道路面排水等设施和方法;用更加科学的管理手段,加大规范化,精细化施工,确保隧道施工质量。

AbstractFlat line selection of highway tunnel shall obey the general route trend. Although within route adjustable range, good geological position should be selected, and long tunnel geological conditions are more complicated. Especially when there are loessweak mudstonemylonite zone and breccia rock crushing areaduring tunnel excavation, water seepage and gushing are appear. According to the experience in recent years in the construction of the tunnel and scientific researchhalf pipe drainagevertical and horizontal drains, gutters centergeotextiles and waterproof board installation techniques, performance improvements of two impermeable lining, and drainage facilities and road tunnels methods are summarized in this paper so as to adopt more scientific management methodsincrease standardizationrefinement constructionand ensure quality of tunnel construction.
