摘　　要：桥梁基础资料丢失给桥梁养护及桥梁附近地下基建(管廊、地下街等)方案的设计和施工带来障碍。物探方法具有经济、快速、无损的特点,但各种物探方法均有其应用的局限性,本文通过对多种地球物理勘探方法特点的分析,结合桥基探测现场环境,提出了地质雷达法、地面瞬变电磁法与钻孔瞬变电磁法探测桥基分布范围的综合物探技术,实践证明该综合物探技术能对隐伏桥基分布范围进行快速、准确的判定。It's barrier to bridge maintenance and underground construction design for the lost of bridgefoundation information. Geophysical exploration method has the characteristics of economic,rapid and nondestructive,but every geophysical exploration method has the limitations of its application.In this paper,through the analysis of the characteristics of various geophysical exploration methods,combined with the environment of bridge foundation detection,put forward the geological ground penetrating radar method,ground transient electromagnetic method and drillingtransient electromagnetic methodto detect the bridge foundation at the same time. Practice proves that the integrated geophysical exploration technique canjudgedistribution range of bridge foundationrapidly and accurately.
