摘　　要：在堤防隐患检测的众多方法中,地球物理方法以快速、无损的特点被广泛使用。采用单一的物探方法,会受到探测结果多解性的约束,导致检测结果可能不合理。采用地质雷达法、高密度电法、天然面波法,对上海浦东新区某段堤防进行综合地球物理探测。结果表明,基于不同物性的异常,可有效地判断隐患的分布,提高了检测结果的准确性,为后期堤防的安全运营和综合治理提供了依据。Geophysical prospecting method is widely used in detection of embankment hidden danger because of its fast and nondestructive characteristics.Using a single geophysical method will be constrained by multiplicity of detection results,which may lead to unreasonable detection results.GPR method,high density electrical method and natural surface wave method are used to detect a section of embankment in Pudong New Area of Shanghai.The detection results show that distribution of hidden dangers can be effectively judged based on anomalies of different physical properties,which improves accuracy of the detection results,and provides a strong basis for safe operation and comprehensive treatment of later embankment.
