摘　　要：引调水工程的勘察是一项比较复杂且繁重的任务,特别是大埋深引水洞线,深部地层构造发育比较复杂,从地表向下无规律可循,单一的物探方法容易受到多解性或其他条件的限制,精度很难保证。该文通过用V8和EH-4两种电磁法进行原位对比测试,对测试结果进行分析,总结出不同电磁法的使用条件及优缺点,研究成果可为此类工程的勘察提供借鉴。The investigation of water diversion project is a more complex and heavy task,especially the investigation of large buried deep water diversion tunnel line.The development of deep stratum structure is relatively complex,and there is no rule to follow from the surface downward.The single geophysical exploration method is easy to be limited by multi-solution or other conditions,and the accuracy is difficult to guarantee.Using V8 and EH-4 electromagnetic methods,we analyze the test results,and summarize the use conditions and advantages and disadvantages of different electromagnetic methods,which can provide reference for the investigation of such engineering.
