| 摘 要： | 在广西柳州地区特高压线路建设中,利用高密度电法对溶洞进行探测,然而探测结果难以判断高阻异常是充气溶洞的响应还是石灰岩本身的高阻特性响应。在高密度电法探测结果的基础上,进一步使用探地雷达对异常模糊区进行复测验证,雷达结果中出现形如双曲线的反射异常,从而判定高阻异常来源于充气溶洞,而不是石灰岩本身。

| Abstract: | In the construction of UHV lines in Liuzhou, Guangxi, the authors used high density resistivity method to detect underground caves, however, it is difficult to determine whether the high resistivity anomaly is the response of the gas-filled cave or the high resistivity limestone itself. On the basis of high density resistivity method, ground penetrating radar was used to further verify the abnormal fuzzy area. The hyperbolic reflection anomaly in radar result indicated that the high resistivity anomaly is derived from gas-filled cave, rather than the limestone itself. |
