| 摘 要： | 隐伏岩溶的存在对工程危害较大,常规钻探、物探手段对岩溶区桩端持力层勘探存在不足。本文应用电磁波层析成像技术进行桩端持力层探测分析。工程实例表明该方法行之有效,具有较高的探测精细程度,为桩端持力层的确定提供了直观而准确的依据。

| Abstract: | The covered karst is potential dangers to construction engineering. Following a discussion on weakness of general drilling or geophysical methods for load-bearing stratum in karst region, this paper introduces the application of electromagnetic wave computerized tomography in load-bearing stratum detecting and analysis. The engineering demonstrations show that this method has a higher precision and can be used to gain a better effect. |
