Natural source surface wave technology which is a traditional geophysical exploration method is widely used in shallow geological survey and engineering site evaluation.In this paper,the experimental application of natural source surface wave technology in urban geological survey of Urumqi is introduced.By measuring the velocity structure of surface wave at a single point,the strata and structures in the area are delineated,and a number of engineering parameters for site evaluation are obtained.Through application and research,it is verified that natural source surface wave technology can be effectively used in urban areas characterized by dense population,complex environment and serious disturbance.The application process of natural source surface wave technology in urban geological survey is established.The results have guiding significance for the further exploration of urban underground space resources.
