山东烟台白洋河岩溶水系统岩溶塌陷发育规律及易发性评价

近年来，山东烟台白洋河地区发生多次岩溶塌陷，对烟台市城镇化建设、当地居民的财产造成了一定的损失，造成了一定的社会影响。本文以白洋河岩溶水系统为研究对象，采用定性与定量相结合的方法，选取岩溶发育程度、地下水动力条件、覆盖层特征3个一级评价因子，地质构造、基岩富水性、水位变幅、水位与基岩面关系、覆盖层结构、覆盖层厚度指数、覆盖层底板特征7个二级因子，采用层次分析与综合指数法进行易发性评价，为防灾减灾提供地质依据。

Development Regularity and Susceptibility Evaluation of Karst Collapse in Baiyanghe Karst Water System in Yantai City in Shandong Province

In recent years, many karst collapses have taken place in Baiyanghe area in Yantai city. It has caused certain losses to urbanization construction and the property of local residents. In this paper, taking Baiyanghe karst water system as the research object, seleting karst development degree, groundwater dynamic conditions and overburden characteristics as first-level evaluation factors, geological structures, water abundance of bedrock, amplitude of water level, relationship between water level and bedrock surface, overburden structure, overburden thickness index, and overburden floor characteristics as seven secondary factors, by using Analytic Hierarchy Process (AHP) and Comprehensive Index Method, the vulnerability has been evaluated. It will provide geological basis for disaster prevention and mitigation of related departments.
