Predominant Period of Laterite Site Based on Microtremor H/V Spectral Ratio Method
摘要
Abstract
To study the applicability of the H/V spectral ratio method for determining the predominant period of laterite sites,we conduct systematic microtremor measurement on different classifications of laterite sites and process the microtremor measurement data using different combinations of horizontal components in the H/V spectral ratio method to get the HVSR curves.We analyze the HVSR curves to obtain the predominant period of the sites,and then determine the site classifications and divide the site geotechnical types.Finally,we verify the applicability of the microtremor H/V spectral ratio method for determining the predominant period of laterite site by borehole exploration.Moreover,u-sing the combination of the sum of east-west and north-south vectors as horizontal components in the micro-tremor H/V spectral ratio method can obtain the predominant period of the site more easily and accurately.关键词
