【摘要】 随着国内交通事业的高速发展,需要修建大量深理长大山岭隧道。在高水压岩溶区修建隧道在国内外都是个技术难题,尤其在当今对环保要求较高的条件下,不能肆无忌惮地排放地下水,而是以“防、截、排、堵相结合,因地制宜”的原则进行。许多已建和在建的山岭隧道都告诉我们,因高水压所引发的各种岩溶地质灾害比比皆是,给隧道的施工乃至今后的运营都构成了很大的威胁。岩溶隧道的衬砌水压力特征分析和岩溶处治技术已经成为设计和施工中需要考虑的重点问题,已经引起各国有识之士的极大关注。本文以齐岳山隧道为工程背景,通过理论分析、数值模拟和现场监测等手段,对齐岳山隧道衬砌水压力特征与岩溶处治技术进行了研究,主要研究内容和成果如下：1、根据齐岳山隧道的工程地质和水文地质条件,分析了齐岳山隧道岩溶发育的基本特征。2、通过理论分析、数值模拟和现场监测等手段,分析了齐岳山隧道衬砌水压力特征。3、依据齐岳山隧道工程实例,研究了隧道岩溶分类方法和处治原则,并在此基础上提出了分类处治的方针,形成了系统和科学的相应成套处理模式和技术方案。更多还原

【Abstract】 The rapid development of communications career at home poses an increasing demand of deep, long mountain tunnels. It’s a challenging technical problem to build tunnel in high hydraulic pressure karsts area at home or abroad, particularly under the current stringent environmentally-friendly prerequisite. We should not drain ground water without thinking, but should be updated with ’combined with preventing,cutting,draining and plugging and adaptation to local conditions’. Many mountain tunnels been built and building tells us that various kinds of karst geological disaster caused by high hydraulic pressure is everywhere, poses a great threaten to construction and operation of tunnel. The problem to water pressure upon lining and treatment technique upon karst is inescapable during the phase of design and construction, and has aroused tremendous attention from men of insight worldwide. Systemic research is based on the case project of Qiyueshan karst, take means of theoretical analysis and numerical simulation and field monitoring, study on the rule of water pressure upon lining and treatment technique upon Qiyueshan karst. Major research results are as follows:1. Analysising the basic characteristics of karst according to engineering geological and hydrogeological conditions of Qiyueshan karst.2. Studying the water pressure upon lining by means of theoretical analysis and numerical simulations and field monitoring.3. Studying the classification and treatment principles on karst, and proposing the policy of classification treatment on this basis, and forming a complete system and the corresponding processing mode of scientific and technical programs.更多还原
