摘　　要：在松花江干流依兰航电枢纽相关的工程地质勘察中,采用了浅层折射地震勘探、瞬变电磁勘探及探地雷达勘探这3种物探方法,通过3种方法的现场使用及后继相关资料的解释处理可以看出:在实际勘察中,物探多种方法的综合运用效果是理想的,通过与相应测线上的钻孔资料对比,证明精度也是可靠的,且可以减少盲目布置的勘探工作量,降低勘探成本,甚至还可以解决某些常规地质方法难以快速解决的问题。由此看出,综合物探在水利工程勘察领域完全可以达到技术要求,在未来的工程勘察中应大力推广。Three kinds of physical exploration methods composed of shallow refracting seismic exploration,transient electromagnetic exploration and prospecting by ground-penetrating radar were adopted for relative geological exploration of Yilan navigation and hydropower key project located on the main Songhua River. Based on the three methods used and subsequent information,it can be seen that the comprehensive usage effect of various physical exploration methods is ideal,it proves that the accuracy is dependable through comparison for drilling hole information about corresponding survey lines,meanwhile,not only mutually reinforcing but also may reduce the blindness in the exploration work quantities and exploration cost,even may solve the problems difficulty to be solved with some conventional geological methods. It can be seen that simultaneous application of various physical exploration methods in the field of hydraulic engineering exploration can completely meet the demands of technology and should be popularized energetically for future project exploration.
