本文采用地质调查、钻探、物探等方法对粤北英德某厂址进行了岩溶调查与研究。基于单孔线溶率和分段遇溶率统计,结合物探结果,阐明了研究区岩溶的分布基本特征。通过对其地质特征进行分析研究,发现受地质因素的控制,区内易发育岩溶,但形成地下河和厅堂式溶洞的可能性小;南部灰岩区岩溶强烈发育,北部泥灰岩区岩溶中等-微弱发育;断裂附近地段岩溶极强烈发育,且局部地段垂直岩溶发育。
In this paper, geological survey, drilling, geophysical and other methods of a site in northern Guangdong Yingde karst survey and research. Based on the single-hole line rate and case-by-case statistics, combined with geophysical results, the basic characteristics of karst distribution in the study area are clarified. Through the analysis of its geological characteristics, it is found that under the control of geological factors, karst development is easy to develop in the area, but there is less possibility of forming underground rivers and hall-type karst caves; the karst in the southern limestone area is strongly developed; the karst in the northern marlstone area is medium- Weakly developed. The karst area near the fault is very strongly developed and the vertical karstification develops in some areas.
