摘要

摘要: 淮南市舜耕山地区位于华北板块南缘，岩溶地貌发育且岩溶塌陷地质灾害时有发生，给区内人民生命财产安全带来极大隐患。本文通过对区内碳酸盐岩裸露区和覆盖区岩溶野外地质勘查、岩溶塌陷特征统计、构造及水文地质条件分析，总结本区岩溶塌陷发育机理。结果表明：裸露型碳酸盐岩区岩溶塌陷发育主要受本区多期构造运动以及岩性组合的影响，岩溶塌陷发育构造形迹呈NW向居多，并多发育在可溶岩与非可溶岩界面处，以构造破坏-潜蚀为主；覆盖型碳酸盐岩区岩溶塌陷发育多为地面构筑物增加导致静荷载增加以及矿区强排水诱发的塌陷，以有效应力破坏-真空吸蚀为主。

Abstract: The Shungeng mountain of Huainan City is located in the southern margin of North China plate. The karst landforms are well developed and the geological hazards of karst collapse occur frequently, which bring great potential disasters to people’s life and property in the region. Based on the karst field geological investigation, the statistics of karst collapse characteristics and the analysis of structural geology and hydrogeological conditions in the exposed and cover areas of carbonate rocks in the area, the karst collapse development mechanism in this area is summarized. The results show that the development of karst collapse in the exposed carbonate area is mainly influenced by the multi-phase tectonic movements and lithologic assemblage in this area; and the extension of the karst collapses are mainly in NW direction and most of them are located at the interface between soluble and non-soluble rocks, of which the formation mechanism is mainly structure destruction and underground erosion. The development of karst collapse in covered carbonate rock area is mostly caused by the increase of ground structures, which leads to the increase of static load and the collapse induced by strong drainage in the mining area. The formation mechanism is dominated by effective stress failure and vacuum inhaling corrosion.
