| 摘 要： | 荷叶塘高架桥桥位区岩溶强烈发育。为查明各桥墩位置深部岩溶发育的类型、规模，勘察中采用了跨孔电磁波透视法。结合钻探和跨孔电磁波测试结果对该桥桥墩位置深部岩溶发育的规律进行了分析，对跨孔电磁波测试的验证和效果进行了讨论。钻孔验证表明跨孔电磁波透视法探测精度较高。综合分析表明，可应用跨孔电磁波透视法成果作为确定桩基础持力层的辅助依据。

| Abstract: | Karst is developed intensely in Heyetang viaduct.The cross hole electromagnetic wave penetrating method has been used to detect type and scale of karst in Heyetang viaduct.The law of deep karst of the viaduct has been analysed according to achievements of drilling and cross hole electromagnetic wave penetrating.Testing and effection have been discussed and evaluated.According to testing of drilling ,we have found that detecting precision of cross hole electromagnetic wave penetrating is high. The comprehensive analyzing has made known that cross hole electromagnetic wave penetrating method can be used to be an auxiliary mean on determining bearing layer of pile foundation. |
