| Abstract: | This paper expounded the stratigraphic classification and the age determination of sandy gravel in Gobi Desert, northweast of China. Based on the observation data obtained from the seismotectonic zoning and important structures building in northwest area,the paper analyses the characteristics of microtremor about sandy gravel site and studies the relation between the spetral specification of microtremor and site parameters. Furthermore it also discusses some questions as to the significance of testing and analysing of ground microtremor in engineering etc. |
