摘要: 开展地下水位预警研究有助于中国北方覆盖型岩溶分布地区地下水资源开采的调蓄和岩溶塌陷地质灾害的预防。文章提出了此类地区岩溶地下水水位预警线的划定方法，基于统计分析绘制长序列监测水位的最小值、第5、第25、第75百分位值曲线作为地下水位预警判据模板，以基岩面附近的水位波动阈值和水位低于基岩面的深度建立岩溶塌陷地下水位预警判据模板，最终建立综合预警判据模板并确定分区预警结果。将该方法用于山东省泰安市城区-旧县岩溶水系统，通过2015年和2016年的单点预警结果和分区预警结果进行对比分析，认为该方法预警结果与实际情况基本相符，具有可推广性。

Abstract: Research on Groundwater Level Warning (GLW) is helpful for the regulation of groundwater resources development and the protection of the geological disaster of karst collapses in covered karst areas in northern China. This paper proposed a method for the delineation of karst GLW. Specific steps include, (1) establish the criterion of GLW based on statistical analysis of groundwater level monitoring data and plot the minimum,5th,25thand 75th percentile curve of water level; (2) establish the criterion of GLW for karst collapse in line with the threshold value of water level fluctuation around roof of bedrock and beneath the roof when collapse happened; (3) firstly,establish the comprehensive judgment criterion model to determine the GLW of a single observation well ,and determine the GLW divisions based on observation wells cluster finally. This method was verified in the Chengqu-Jiuxian karst system of Taian City in Shandong Province. According to the comparison of warning result of single observation well and GLW divisions between 2015 and 2016, the method was proved to meet the actual conditions and was reliable to be promoted. -
