| Abstract: | In the Shanghai 3D urban geological survey,SH wave reflection method was proven available in subdividing the stratigraphic sequence with buried depth < 80 m,especially in tracing the spacial change of the local hardpan.Relying on this method,the transitional relationship of the hardpan distributed respectively in the western and eastern Shanghai was determined.In this paper,we analyzed the particular engineering-oriented case and evaluated the validity and employing prospect of this method.. |
