| Abstract: | In Northern and Southern China, there are two different territorial systems of karst collapse. Because of the differences in basic geological conditions, groundwater dynamic conditions and climatic factors, the karst collapses are different in Northern China from those in Southern China in types, distribution characteristics, development density, scope, and formation mechanism. Based on analysis of statistical data in bulk and analysis of basic rules of the karst collapses in China, this paper systematically analyzed the basic geological conditions, groundwater dynamic conditions and climatic conditions both in North and South when studied and concluded the discrepancy in features, scales, density, regional distribution rules, formation mechanism, etc. The contrast and rules concluded will be of important significance and have great implication value to the exploration and prevention of karst collapse planning and layout of relevant project construction. |
