Construction and application of vS30 data in Sichuan Province:a case study of the Wenchuan Ms8.0 earthquake
摘要
Abstract
As an important parameter for site classification,the average shear wave velocity at a depth of 30 m(vS30)is widely used in domestic and international seismic design codes for build-ings and structures,as well as in the correction of local site effects.However,the applicability of the vS30 data commonly used in China,which are provided by the United States Geological Survey(USGS),requires further verification.Based on the correlation between terrain slope in Sichuan Province and shallow average wave velocity,as well as the relationship between vS30and shallow average shear wave velocity,this paper proposes a vS30 dataset for Sichuan Province paper.The dataset is then applied to the seismic intensity assessment of the Wenchuan Ms8.0 earthquake.The results show that compared with the widely used vS30 data provided by USGS,the vS30 results for Sichuan Province obtained from this study are closer to the actual situation.The rapid seismic intensity assessment of the Wenchuan Ms8.0 earthquake using the vS30 data in this study provides more accurate judgments of heavy and severe disaster areas.The results can improve the accuracy of seismic emergency outputs in Sichuan Province in the future,offering valuable first-hand refer-ence materials for post-earthquake emergency command and rescue operations.关键词
