| 摘 要： | 自2015年6月以来,在山东滕州荆泉水源地范围内连续发生多起岩溶塌陷。通过研究区域地质条件,在已有认识的基础上分析得出发育的浅层开口岩溶洞隙的存在,一定厚度的松散覆盖层及地下水位大幅下降是该区产生岩溶塌陷的基本条件。阐述了岩溶塌陷形成发育过程及影响因素,得出长期过量抽采岩溶水是区内岩溶塌陷的主要因素,合理减少地下水开采量是预防岩溶塌陷最有效的方法。

| Abstract: | Many karst collapses have been occurring continuously since June 2015 in Jingquan water source area. Through study on regional geological conditions, based on existing research, it is regarded that basic conditions for karst collapse in this area are the existence of shallow open karst caves, a certain thickness of loose covering and the drastic drop of groundwater level. The forming process and influencing factors of karst collapse have been introduced. It is regarded that longterm overpumping of karst water is the main factor of karst collapse. Reducing groundwater extraction is the most effective way to prevent karst collapse. |
