Summary and Inspiration of Survey Results in Kunming Changshui Airport Work Area in Karst Region
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.
