SIR-20多通道透视雷达在桩基岩溶探测上的应用

The application of SIR-20 multi-channel perspective radar in pile foundation exploration

为探测人工挖孔桩孔底3倍桩径或5 m深度范围内是否存在溶洞等不良地质现象,采用高频透视雷达技术,在桩底布设十字交叉探测剖面,并对雷达数据进行处理,推断地下地质结构。经过实际钻孔证明,使用透视雷达是一种行之有效的方法。

In order to detect manual hole digging pile bottom 3 times pile diameter or within the depth of 5 m whether had karst and other adverse geologic phenomena,using high frequency perspective radar technology,on the pile bottom to layout cross exploration profiles,and made data process to radar,infered subsurface geological structures,through the actual drilling to prove,using perspective radar was an effective method.
