| 摘 要： | 云贵铁路石林隧道穿越滇东高原岩溶区，隧址区岩溶极为发育，对隧道施工影响较大。为了能选择较好的隧道穿越方案，通过对隧址区工程地质条件及地下岩溶水系统发育特征进行深入的调查和分析，最终确定“抬升轨面标高，避开水平循环带，大角度穿越构造”的方案。

Research on the Karst Development Characteristics of Shilin Tunnel and Selection of Crossing Plan |
| |
| Abstract: | Shilin tunnel on the Yunnan-Guizhou railway is located at the area of Eastern Yunnan plateau, where the karst is highly developed. It has significantly negative influence on the construction of tunnels. To develop a better program on the tunnel crossing, this study proposes a scheme, named "uplift the elevation of rail level, avoid horizontal cycle belt of cavern water, cross the tectonic structures with large angles" based on the detailed field investigation and analysis of the local geological conditions and the development characteristics of underground karst water system. |
