Abstract Under the condition of deep overburden,it is important to economically and quickly judge the complex geological problems in hydropower engineering survey.Surface wave exploration technology with field source compensation has the advantages of economy,rapidity,good stability and little interference from outside.It has been applied in many fields with good results achieved.Starting with complex geological problems and based on comparing and analyzing the detection effects of high density resistivity method,magnetotelluric method and surface wave exploration method,the authors hold that the large depth surface wave detection technology can effectively avoid the influence of complex geological conditions in surface layer,improve the detection depth and accuracy to a certain extent and solve geological problems in a certain range.
