Application of Groundwater Model for Risk Assessment of Karst Collapse in Linyi City
摘要
Abstract
The karst collapse is the most important types of geological disasters in Linyi city of Shandong province. Once the occurrence of karst collapses, it may lead to greater economic and property losses, so it should be very necessary for risk control and prediction of karst collapse. Risk assessment includes current situation evaluation and forecast evaluation, mainly consists of three steps: hazard assessment, vulnerability assessment and expected loss evaluation. This paper adopts the fuzzy comprehensive evaluation based on AHP method in risk assessment firstly, then vulnerability assessment and expected loss evaluation is given, and a comprehensive assessment classification map of present situation is developed. The risk of karst collapse is predicted using the groundwater flow model with witch the relevant evaluation factor is determined by the adjusting groundwater pumping scheme. By comparison, the high risk area of karst collapse is greatly reduced through adjusting pumping scheme. It has important significance to prevent occurrence of karst collapse by the reasonable karst water pumping scheme with the combination of numerical model of groundwater flow and risk assessment methods.关键词
