Engineering Geological Database for TSMIP

Engineering Geological Database for TSMIP

More than 680 seismic stations all over Taiwan have been established by the Central Weather Bureau(CWB) to record ground motion data. In order to obtain the geological conditions and soil profiles at these strong motion stations, a site investigation project was developed by the National Center for Research on Earthquake Engineering(NCREE) and CWB in 2000. The site investigation mainly consists of three parts:(1) the basic description of a site,(2) the on-site boring, and(3) the Suspension P-S Logger technique, which was used to determine the P-wave and S-wave velocities of the strata at various depths. The Suspension P-S Logger technique, using a single down-hole probe with one source and two receivers, allows continuous measurements of wave velocities with high resolution. There were 21 seismic stations investigated in 2010. With reference to Kyoshin Net in Japan and ROSRINE in the USA, a preliminary engineering geological database for 448 seismic stations investigated from 2000 to 2009 has been constructed on the Engineering Geological Database for TSMIP(EGDT) website for researchers’ convenient access to their needed data.
