摘要: 针对江山港岩溶区某段河道内可能存在的隐伏溶蚀体,提出了采用拟地震化供电方式且同步采集海量数据的并行电法为主要探测技术手段,并结合 钻孔揭露资料,分析了岩溶体在河道两岸下方的平面展布,进一步预测河床底部区地层的构造特征。试验研究表明:二维视电阻率断面揭示出整个测线控 制区域的岩溶体的二维分布,有效地勾勒出溶蚀洞体在垂面上的埋深、大小及规模等信息;考虑到两岸溶洞在河床底部的关联性问题,提取不同深度的电 阻率立体化切片,直观地显示出河道两岸溶洞在垂向上分布高程不一、大小差异明显以及右岸溶洞在河床内延展但并未贯通至左岸的特点,研究成果为流 域综合治理以及后期运行维护提供科学地技术支撑。

Abstract: As for the possible concealed corrosion body that may exist at certain section of watercourse in Jiangshan Port karst area ,the parallel electric method which adopted quasi-earthquake power supply mode and synchronous acquisition of a huge amount of data was proposed as the main means of detection technology.Besides,combining with drill disclosure data,the plane distribution of karst body under the sides of watercourse was analyzed.The structure characteristics of the riverbed bottom area were further predicted.According to the experimental study results,it is indicated that two-dimensional apparent resistivity section reveals the two-dimensional distribution of the karst body in the whole exploration line control area,which effectively outlines the buried depth ,size and scale of corrosion body piercing in the vertical plane.Because of the correlation of karst caves of both sides at the bottom of the riverbed,the three-dimensional sections of resistivity with different depth were extracted,which intuitively showed that both sides of karst caves were obviously different in elevation and size on vertical distribution; the right bank of karst caves extended within the riverbed,but it didn’t reach the left bank.The research results provide scientific and technical support for the comprehensive reclamation and later operation maintenance of the river basin.

Key words: hydraulic engineering, parallel electrical method, covered karst, cavern survey, 3D resistivity
