复杂地层环境下岩溶坍塌分析与处置
Analysis and Disposal of Karst Collapse in Complex Geological Environments

岩溶塌陷是隧道施工中常见的地质灾害，尤其在岩溶地貌发达的西南地区，常受到自然因素与人为活动的交互作用影响，给隧道开挖及周边环境带来严重影响。因此，研究复杂地层环境下的岩溶塌陷机理具有重要意义。本文结合某地铁隧道施工案例，分析了岩溶塌陷的主要诱发因素，并针对已发生的典型岩溶塌陷问题进行探讨，提出了相应的防治措施及现场处置方案，以期为类似工程提供参考。
During tunnel construction, karst collapse is a common geological hazard, especially in the southwestern region with developed karst landforms. The interaction of natural factors and human activities has a huge impact on tunnel excavation and the surrounding environment. Therefore, it is necessary to study the mechanism of karst collapse in complex geological environments. This article combines a construction case of a subway tunnel to analyze various triggering factors that cause karst collapse, and analyzes and deals with typical karst collapse problems that have already occurred. Corresponding prevention and control measures and on-site disposal measures are proposed.
