Soil Profile Database and Site Classification for National Strong-Motion Stations in Western China

Abstract: As part of a broader effort to develop ground-motion data resources for China in a manner consistent with Next Generation Attenuation projects, we develop a database of geotechnical soil profiles and shear-wave velocity (VS) logs for sites having ground-motion accelerometers (this database is referred to as soil profile database [SPD]), and then use that data to develop site parameters. The site information is compiled for stations within the National Strong Motion Observation Network System (NSMONS) of China.… Show more

“…77.98%), the proposed method has advantage in terms of its capability in identifying sites of class E, and probably class B that inferred by the qualitative evaluation, rather than validated quantitatively by real boreholes. And the reliability in the study area and applicability out of the study area of the proposed method are verified by using the V S30 data of strong motion station provided by Xie et al (2022). Each proxy method for site classification has certain advantages and disadvantages.…”

“…Validation by borehole data provided in the study by Xie et al (2022) We selected part of the strong motion stations with V S30 data under Quaternary units provided in the study by Xie et al (2022; a total of 252 data, of which 101 data are in the XJ area and 151 data are in Sichuan, Yunnan, and Gansu), and the code of each station and the corresponding geological ages and the site classes assigned under the different methods are shown in Supplementary Appendix Document 1. To verify the reliability of this method in the study area, and to test its applicability in other areas outside the study area, the station data were divided into two parts: the XJ area and the area outside the XJ area.…”

“…The black and red dashed lines denote the standard deviations of GMPEs. The fault distance is evaluated as the closest distance between the fault plane and the station into two classes, i.e., rock and hard soil, according to the average shear-wave velocity within 30 m in depth (Vs30) (Xie et al 2022), the predominant period of the H/V response spectral ratio or field survey, we employ the black curves to show GMPEs for the rock site and the red curves for the hard soil site. The observed PGAs are comparable with the predicted PGAs within one standard deviation at target stations except the 51BXD station, where the observed PGA is abnormally larger than the predicted PGA.…”

“…The site parameter V S30 of the strong motion stations of the NSMONS in Gansu Province was calculated from the shear velocity (V s ) profiles provided by Xie et al (2022a). For the strong motion stations of the NSMONS in Qinghai Province, the borehole depth was less than 30 m; and the V S30 was calculated using the regional extrapolation model of northwestern China developed by Xie et al (2022b).…”

“…There are many mountains, including the Tuolaishan, Datongshan, Dabanshan, Lenglongling mountains, distributed to the WNW and ESE of the seismic fault. Therefore, the higher short-period ground motion values in the rupture forward direction may be related to the topographic amplification of the ridge area, and the topographic effect of the mountainous areas mainly amplifies the short-period ground motion (Zhang et al, 2021;Xie et al, 2022a).…”
