Estimation of Seismic Parameters and Shear Waves Velocity from SPT for the Site of Construction Project of Multi Stories Building in Holy Karbala City-Iraq

摘要

Shear wave velocity is an important parameter with respect to geophysical investigation, site classification and microzonation studies. Standard penetration test is very important test in geotechnical works and it spread in all the world. This study had been carried to calculate of shear wave from SPT test for site of construction project of multi stories building in Sacred Karbala Center in Alsadiyah District, Holy Karbala, Iraq. Research methods included field, laboratory and office works. Soil section show sandy soil layers with values of N range between (26) to (50/2 ~( " ) ). The value of shear wave velocity calculated as (396 m/sec).
