自20世纪90年代未以来,由于人类工程活动的加剧,广州市花都区赤坭镇一带多次出现严重的岩溶地面塌陷活动。本文依据实地岩溶地面塌陷地质灾害勘查资料,系统分析了赤坭镇岩溶地面塌陷的分布、规模和危害程度;研究结果表明,赤坭镇岩溶地面塌陷的形成原因主要是人工开挖形成负地形采石场和过量抽排地下水造成。在此基础上,针对赤坭镇岩溶地面塌陷的实际情况,提出了岩溶地面塌陷地质灾害的防治对策。

Since 1990s,due to the exacerbation of human construction,there has been serious karst surface-collapse geological disaster in ChiNi Town in Guangzhou Hua Du area.Based on exploration data on the spot,this text analyse the distribution and development features of karst surface-collapse in ChiNi Town systematicly.Studies have shown that the mian cause of the collapse is artificial formation of negative terrain quarry excavation and excessive pumping of groundwater.On this basis,in accordance with the reality of ChiNi Town karst surface-collapse,putting forward some countermeasure about prevent karst surface-collapse.
