| 摘 要： | 为更加系统全面预测和了解可能在隧道施工中遇到岩溶,根据岩溶发育规律和特点,建立了岩溶在水平岩层、倾斜岩层、背斜岩层、向斜岩层地质构造条件下不同节理发育程度和不同位置隔水层情况下的岩溶发育地质模型,根据隧道工程所处的地质环境,利用地质模型判断未开挖岩层中的岩溶发育类型、规模等情况,并结合物探和超前钻探等方法实现隧道未开挖段岩溶的超前预报。实际揭露岩溶情况与预测结果对比表明,岩溶发育地质模型可以从宏观上比较准确地预测隧道未开挖段的岩溶发育情况。

| Abstract: | To forecast and understand Karst that may be encountered in tunnel construction more systematically and more comprehensively, in this paper, based on the rules and characteristics of karst development in the horizontal rock, inclined rock, anticline rock and syncline rock, the Karst geological models in different relationship of water-resisting layers and joint development extent are established. According to the geological conditions of the tunnel project, geological models are used to estimate the type and size of karst in un-excavated section of rock in tunneling. Then, combined with geological prediction methods such as geophysical prospecting and drilling ahead method, details of Karst can be predicted. Comparison of the actual karst circumstances and the forecast results showed that by the karst geological model, a more accurate judgment of karst development in unexcavated section of the tunnel in a macro level could be made. |
