摘　　要：云贵高原是喀斯特地貌分布较广的地区,类型较多,岩溶作用形成地下架空结构,破坏了岩体的完整性,增加了岩体渗透性,导致下伏溶洞顶板坍塌、土洞发育而形成大规模地面塌陷,碳酸岩基岩面参差不齐,同时基岩面上存在特殊性质的地表风化产物红黏土。文章通过昆明长水机场工作区岩溶地区综合勘察,对岩溶发育规律、红黏土空间特点及性能等成果的总结,提出喀斯特地区勘察范围不同建(构)筑物岩溶问题整治措施,进一步突显岩溶地区综合勘察的优点。Yunnan-Guizhou Plateau is an area with a wide distribution of karst landforms,with many types.Karst processes form underground elevated structures,which damage the integrity of the rock mass and increase its permeability.This leads to the collapse of the underlying karst cave roof and the development of soil caves,resulting in large-scale ground collapses.The carbonate rock foundation is uneven,and there are special surface weathering products such as red clay on the bedrock surface.The paper summarizes the development laws of karst,spatial characteristics and performance of red clay in the karst area of Kunming Changshui Airport work area through comprehensive investigation,and proposes measures to address karst problems in different buildings(structures)within the scope of karst area investigation,further highlighting the advantages of comprehensive investigation in karst areas.
