摘要
该文主要讨论了天然电场选频法在地下岩溶空洞及土洞勘查中的应用。以湘潭宾馆扩建工程探测为例,采用天然电场选频法探测地下隐伏土洞或岩溶分布,查明了溶洞的位置及埋深。通过钻探验证可知,物探解释成果准确可靠。该工程说明物探资料可为地基处理及桩基处理提供合理化建议。
This paper mainly discusses the application of natural electric field frequency-selection method in underground karst cavity and soil cave.As Xiangtan hotel expansion project as an example,the underground concealed soil cave or karst distribution are detected using the natural electric field frequency-selection method,and the location and buried depth of karst is found out.Through the drilling analysis,the geophysical interpretation results are accurate and reliable.At the same time,the geophysical results may provide the rational suggestions for foundation and pile foundation treatment.
