| 摘 要： | 塌陷灾害的发生直接影响着秀宁隧道大皮坡-中村段沿线工农业生产和城镇居民生活，本研究以地质环境与隧道建设活动为基础，分析了区内塌陷的发育特征，揭示本区塌陷在隧道建设前后存在三个发生期:缓慢出现期、集中爆发期、后续影响期；本区塌陷发育存在四个阶段:初始稳定阶段、应力初步变化阶段、塌陷阶段、阶段性稳定阶段，并得出月累积降雨量210～290 mm为本区塌陷发生的临界降雨强度；进一步对本区岩溶富水带塌陷发育模式、断裂带塌陷发育模式进行了讨论，并通过引入塌陷斜率因子μ对区内不同地段潜在塌陷能力进行了对比分析，据此提出了防治措施。

| Abstract: | The Dapipo-Zhongcun tunnel in Yunnan is an area where karst collapses frequently occur. The karst collapses have an important impact on the local industry and agriculture production, the daily life the local residents. It is of important significance to grasp the development regularity and formation mechanisms of the karst collapses. Based on the basic characteristics of geological environment of the study area, this article analyzes the temporal and spatial distribution of the karst collapses and reveals three emergence periods of the karst collapses: the slow emergence period, concentrated outbreak period and subsequent influence period. According to the standard of the main influence factors, the karst collapses in the study area are divided into four basic stages: the initial stable stage, initial change in stress stage, collapse stage and periodically stable stage. The formation mechanisms of the karst collapses are analyzed and grouped into two types. The corresponding prevention and control measures are also proposed. The research results may provide references for the improvement of local environmental conditions and control of geological disasters. |
