摘要
机场跑道潜在的岩溶隐患将直接影响其承载能力和使用寿命。通过广州白云机场跑道的勘察试验研究,表明等值反磁通瞬变电磁法能够在机场噪声背景以及有限不接地场地条件下实现快速无损探测机场跑道隐伏岩溶地质病害,有效规避了地震反射波受机场飞机起降噪声的影响、高密度电法受场地接地条件的制约以及探地雷达探测深度不足等常规工程物探方法的缺点,为机场跑道隐伏地质病害探测提供了一种新的探测方法。
The potential karst disease of the airport runway is directly related to the carrying capacity and working life of the airport runway. According to the applied exploration cases of Guangzhou-Baiyun international airport,the opposing coils transient electromagnetic method in karst disease survey is proved to be fast and non-destructive under the background of airport noise and limitation of the site condition. Compared with conventional engineering geophysical prospecting method,the opposing coils transient electromagnetic method can effectively avoid the influence of airport aircraft landing noise while the seismic reflection wave method fails to do so,and it can work under the condition of poor ground while the high density resistivity method can not do so. What＇s more,it can detect deeper bodies while the geological radar method can not do so. In conclusion,the opposing coils transient electromagnetic method is a new effective detection method for the detection of hidden geological diseases in the airport runway.
