| 摘 要： | 通过分析临沂市城区岩溶塌陷与地下水活动的关系,确定了岩溶塌陷的主控因子为地下水水位。借助已建立的地下水流模型,提出控制岩溶塌陷的方法,即使岩溶水水位不低于控制水位。以此为目标在研究区选定若干具有代表性的水位控制点,并设计了三种地下水规划开采方案,将其带入地下水流模型演算,最终获得合理的地下水开采方案,即未来城区岩溶水开采量与现状开采相比减少了11.65×104m3/d,减少的水量由临沂市岸堤水库地表水工程解决。该方案实施后可在一定程度上控制岩溶塌陷发生的危险。

| Abstract: | By analyzing the relationship between karst collapse and groundwater in Linyi urban area,the key factor leading to karst collapse is determined,i.e.the groundwater level,and the method of controlling the risk of karst collapse is given according to the groundwater numeric model established.In order to control the risk of karst collapse,the water level of karst aquifer should not be lower than the controlled groundwater level.On this account,the trend of dynamic change of groundwater is calculated by the num... |
