【摘要】 论文基于电测深技术研究四川省泸州市叙大铁路震东车站岩溶,通过电测深推测路基岩溶的空间分布与规模,结合钻孔进行综合研究,为岩溶治理提供基础资料。本文首先介绍车站的地质环境条件并分析岩溶成因,择优选择直流对称四极电测深进行岩溶勘察;然后介绍对称四极电测深野外工作及资料处理,反演推测出路基岩溶分布及规模;再通过钻孔验证,电测深推测的土石界面、溶洞,与钻孔揭露吻合度非常高;最后通过电测深和钻孔综合研究,总结围岩与溶洞电阻率的关系及岩溶发育特征,为路基岩溶治理提供基础资料。更多还原

【Abstract】 Based on electrical sounding technology,this paper investigates the karst at Zhendong station of Xuda railway,Luzhou City,Sichuan Province.Based on electrical sounding technology,it is inferred that the spatial distribution and scale of subgrade karsts,combined with drilling comprehensive research,provide basic data for karst treatment.Firstly,this paper introduces the geo-environmental conditions of the station and analyzes the causes of karstification,and chooses the symmetric symmetric four-pole electrical sounding method for karst investigations.Then,the symmetric four-electrode sounding field work and data processing are introduced.Inversion and infers the karst distribution and scale of the subgrade.It was verified by the later drilling,the earth-rock interface and caverns speculated by electrical sounding,the degree of coincidence with the borehole exposure conditions exposure is very high.Finally,comprehensive study of electrical sounding and drilling,summarize the relationship between the surrounding rock and the resistivity of the cavern,karst development characteristics.Provide basic data for subgrade karst treatment.更多还原
