地质分析法在隧道岩溶探测中的应用

在碳酸盐岩地区隧道施工过程中，岩溶地质灾害是常见的地质灾害，往往造成重大经济损失及人员伤亡．地质分析法是隧道施工地质预报的1种基本方法，也是所有采用地球物理探测方法进行隧道施工地质预报的基础．结合具体工程实践，在对碳酸盐岩发育地区岩溶发育条件及发育规律总结归纳的基础上，采用地质分析法，通过对杭瑞高速公路毕都段街上隧道所揭露的岩性、构造、地形及附加岩溶发育情况等进行调查与分析，得出岩溶发育的重点区域，并在实际开挖当中得以验证．

Application of Geologic Analytic Method in Karst Cave Exploration

The karst geological disaster is a common geological one, which often causes significant economic losses and casualties in the process of the tunnel excavation in the carbonate rock area. The geologic analytic method is a basic method of geologic prediction during the tunnel construction and it is also the basis of all the geologic prediction by the geophysical exploration methods during the tunnel construction. In this paper, associated with the concrete practice of engineering and based on the summary of the conditions and regularity of the karst development in the carbonate rock development area, the lithology, structure of rocks, topography, the additional karst development and so on are investigating and analysising by geologic analytic method in the Jie-shang tunnel of the Bidu section of the Hangrui highway, then the key regions of the karst development which are proved in the actual excavation are got.
