岩溶地面塌陷形成机理与成因模式研究——以山东泰安—莱芜为例

Study on the Mechanism and Cause Mode of the Karst Collapse——Taking Tai'an-Laiwu for Example

山东省泰安—莱芜地区自20世纪70年代中期开始就陆续由于岩溶水的排除而出现严重的地面塌陷,属于隐伏灰岩区岩溶地面塌陷,给当地社会和经济发展带来了巨大危害。总结归纳了该地区岩溶地面塌陷的时空分布特征,论述了其产生的地质条件和人为诱发因素,探讨了岩溶地面塌陷的形成机理,并针对存在的问题探索了其成因模式,最后给出了今后该类研究的思路。

The fearful karst collapses have been produced in succession since 1970s by the exploitation of karst water in the area of Tai＇ an-Laiwu, Shandong province. The limestone buried by Quaternary System grows into karst caves, and karst collapse brings enormous harm to the local society and economy development. The spatiotemporal distributing characteristics of karst collapse are summed up in detail. The geological condition, artificial function and forming mechanism of karst collapse are discussed. The cause mode of the karst collapse aiming at the existing questions is discussed and the idea for karst collapse studying in the future is given at last.
