摘要
该隧道通过地层主要为上古生界下石炭统（Ｃ１）石灰岩，占隧道长度的９５％，属浅埋岩溶隧道。其岩溶发育在地质历史上有一个特定的形成过程，并且受构造影响，形成了独特的岩溶特征，此类岩溶形态构成了特殊的工程地质问题。
The main stratum the tunnel passes through is limestone of Carboniferous Series(Cl) of Palaeozoic Group, taking 95% of the total length. In the geological history, thekarst development underwent a special process which was influenced by the tectogenesis,formins a unique karst feature. The karst of this type for,,is a series of special engineeringgeology problems.
