摘　　要：在高速公路建设过程中,岩溶发育带来的各种问题频发,受各种自然条件的限制,单一的勘探技术具有局限性,加大了岩溶区勘察难度,对现有勘察技术提出了新的要求。文中以云南某高速公路岩溶区桥梁勘察为研究对象,通过工程地质调绘、等值反磁通法、地质雷达法、钻探、孔内测试等勘探手段的综合应用,对勘探成果进行对比分析,提高了岩溶区勘探资料的准确性,为岩溶地区的勘察提供经验参考,为桥梁设计提供可靠的地质依据。In the process of expressway construction,various problems caused by karst development occur frequently.Due to the limitations of various natural conditions,a single exploration technology has limitations,which increases the dfficulty of karst area exploration and puts forward new requirements for the existing exploration technology.Taking the bridge survey in karst area of a highway in Yunnan Province as the research object,the paper compares and analyzes the exploration results through the comprehensive application of engineering geological mapping,equivalent anti-magnetic flux method,geological radar method,drilling,in-hole testing and other exploration methods,improves the accuracy of exploration data in karst area,provides experience reference for the survey in karst area,and provides reliable geological basis for bridge design.

关 键 词：等值反磁通法 地质雷达法 综合勘探 岩溶地区 桥梁勘察
