地下空洞通常会作为公路建设和民用建筑的改造过程中的一种潜在隐患,时待施工物品产生内在威胁,不利于建设的进行。有效地运用瑞雷面波,高密度电阻率法,探测雷达,弹性渡测试等方法可以检测出地下空洞,便于对其进行处理,有利于施工的进行。 Underground holes usually serve as potential hidden dangers in the process of highway construction and renovation of civil buildings, posing an inherent threat to construction items and not conducive to the construction. The effective use of Rayleigh surface wave, high density resistivity method, detection radar, flexible cross-testing and other methods can detect underground holes, easy to handle, is conducive to the construction.
