摘　　要：岩溶塌陷一直是西南岩溶区工程建设面临的一大难题,准确查明地下岩溶分布规律、发育特征对岩溶地区大型基建项目具有重要意义。该文以云南某机场勘察为例,探讨基于工程地质调绘,采用物探与钻探相结合的探测方法,查明了地下岩溶分布规律、发育特征,为机场岩溶塌陷灾害风险防治提供了依据。Karst collapse has long been a significant challenge in the construction of southwest karst areas,and it is of great significance to accurately identify the distribution law and development characteristics of underground karst for large-scale infrastructure projects in karst areas.Taking an airport investigation in Yunnan Province as a case study,based on engineering geological mapping,this paper utilizes geophysical surveys and borehole drilling to reveal the distribution patterns and development characteristics of subsurface karst formations,providing a scientific basis for risk assessment and mitigation of karst collapse hazards at the airport site.
