摘　　要：为了深入了解广州白云区的岩溶发育规律,本研究收集整理了该区3个毗邻项目的地质勘察报告。通过分析396个见可溶岩钻孔数据,揭示了溶洞的发育规律,包括岩洞的深度、规模及充填物类型等。研究发现,该区域岩溶以中风化至微风化带灰岩层为主导发育,溶洞多呈无填充或半填充状态,并伴随显著的地下水活动。岩溶发育深度近似正态分布或对数正态分布,发育规模差异显著。研究结果为区域基础设施建设的岩溶灾害防治提供了先验性的理论支持,并提出了在施工过程中降低岩溶风险的针对性建议。To gain a deeper understanding on the karst development patterns in Baiyun District,Guangzhou,this paper collected and sorted out the geological survey reports of three adjacent engineering projects in this area.By analyzing the data of 396 boreholes penetrating soluble rock,the development patterns of karst caves was revealed,including the depth,scale and type of filling materials of the caves.It is found that the karst in the area is predominantly dominated by the development of moderately-weathered to lightly-weathered limestone layers,and the caves are mostly unfilled or semi-filled,accompanied by significant groundwater activities.The depth of karst development is approximately normally distributed or lognormally distributed,and the development scale varies significantly.The results of the study provide essential theoretical support for karst hazard prevention in the construction of regional infrastructure and offers corresponding suggestions for reducing the risks of the karst during the construction process.
