摘要
某岩溶发育区的工程桩采用跨孔弹性波CT法测得桩底部岩土体的波速云图,对桩底地质条件进行评估,查明了桩端岩土层和溶洞发育情况。实践表明:跨孔弹性波CT法的物探测试手段具有数据直观的特点,可在溶洞等地下埋藏物探查方面推广应用。
The cross hole elastic wave CT method was used to detect the cloud map of the rock and soil mass at the bottom of the pile in a karst development area.The geological conditions at the bottom of the pile such as the rock and the soil mass of the karst cave were ascertained and evaluated.The practice shows that cross hole elastic wave CT method has the characteristics of data visualization,and can be popularized and applied in the exploration of underground buried objects such as karst caves.
