文摘

Karst collapse is a type of complicated environmental and geological hazard that can be caused by many factors: natural factors, such as rainfall, and human activities, such as overpumping of groundwater. Therefore, it is important to make a comprehensive analysis and evaluation on karst collapse risks and impacts of the influencing factors of karst collapse. However, how these factors affect karst collapse is still a problem, which has not yet been well solved. Taking the karst collapse in groundwater exploitation area of Shiliquan of Zaozhuang, China, as the example, and based on the comprehensive analysis of the formation rule and mechanism of karst collapse in this area, this paper mainly employs Quantification Theory to make a quantitative analysis and evaluation of various influencing factors of karst collapse in the groundwater exploitation area of Shiliquan of Zaozhuang. It thereby determines the impact of different influencing factors on karst collapse strength, and identifies the dominant and minor factors that affect the karst collapse. It also provides some criteria for the prevention of karst collapse and protection of karst water resources and environment.
