摘要
自20世纪80年代以来,临沂市城区一带发生多起岩溶塌陷,这些岩溶塌陷发生具有突发性、重复性,其分布具有一定的规律性;其形成原因一方面取决于该区具备岩溶塌陷形成的物质基础条件,另一方面取决于水动力条件的改变,而水动力条件的改变主要是由于城区地下水不合理开采造成的。
Quite a few of Karst collapses have happened in Linyi city since 80＇s of 20 century. They have the characteristics of abruptness, repetition and differential distribution. Karst collapse was formed by two sides origins： one is basic condition for forming collapse,the other is the change of hydro-dynamic condition which was caused by irrational exploitation of groundwater in city area.
