公路隧道防排水的安全型综合解决方案

Integrated waterproofing and drainage method of highway tunnel

研究了各国矿山法公路隧道防排水问题的现状 ,分析了中国公路隧道防排水存在的几个问题 ,指出防水不是目的 ,应将公路隧道结构的防排水设计与结构的受力、耐久性、安全防灾、通风、维修等问题的设计综合起来考虑 ,以达到从优化结构保障运营安全和延长使用寿命的设计目的 ,并推荐了三种断面形式。

Authors study the waterproofing and drainage technical development of highway tunnels at home and abroad, and analyze the existing problems of Chinese highway tunnel waterproofing and drainage technology. Then, point out that waterproof isn't the ultimate aim, which should be integrated with consideration of the force acted on the structure, durability, safety and fireproofing, ventilation, maintenance of the highway tunnel and etc., so as to reach the designing goal of using optimal structure to guarantee the running safety and the life span of the highway tunnel.In the end,three types of section configuration are given.
