“冲蚀型”岩溶塌陷案例与研究

Case and Study of Scouring Erosion Karst Collapse

通过岩溶丘陵地区的变电站工程实例,从土的特性、岩溶特征、水的下渗作用,对原本稳定的山丘高地,在场地深度平整后触发地面塌陷的原因作研究分析,提出了与"潜蚀型""真空吸蚀型"有本质区别的"冲蚀型"塌陷的观点,从理论与实践上丰富了岩溶塌陷机理,以提高对岩溶塌陷全方位的认识。

Taking a substation located in karst hilly area as an example,this paper analyzes and studies the reasons on ground collapse of the stable hilly area due to deep leveling on the site based on the soil characteristics,karst characteristics,and water infiltration,provides an idea of scouring erosion collapse essentially different from subsurface erosion collapse and vacuum erosion collapse,enriching the mechanism of karst collapse from theory and practice,and improving the comprehensive understanding of karst collapse.
