我国岩溶地质、地貌集中分布于云、贵、川三省及两广、两湖部分地区,随着国民发展需要,西部大开发战略的实施,上述地区基础设施建设力度进一步加大,近期贵广、渝利、兰渝、成兰、沪昆等铁路工程陆续开工建设,需要处理大量由于岩溶地质引起的工程问题,特别是岩溶隧道工程问题。本文结合某线仙人洞隧道突泥治理特点,对大规模冒顶型突泥整治方法作了介绍,为以后隧道岩溶整治提供了施工经验。
Karst geology and geomorphology in our country are concentrated in Yunnan, Guizhou and Sichuan provinces as well as in some areas of Guangdong, Guangxi and Hunan and Hubei provinces. With the development of the national economy and the implementation of the strategy of developing the western region, infrastructure construction in these areas has been further intensified. Recently, , Lan Yu, Cheng Lan, Shanghai Kun and other railway projects have started construction, need to deal with a large number of engineering problems caused by karst geology, especially karst tunnel engineering problems. Combined with the characteristics of outburst control of fairy cave tunnel in a certain line, this paper introduces the method of large-scale roof fall mud treatment and provides construction experience for later karst remediation.
