A seismograph data-based computer program for determination of dynamic soil properties
Abstract
Being obliged to live in one of the most dangerous quake risk carrying and youngest continent-to-continent plate boundary regions in the world brings about importance of geophysical, geological, measurements to be able to assess local strategies to reduce the after effects of earthquakes. The capacity of local geotechnical properties of underlying soft soil on the local amplification during an earthquake is directly related to real time destruction behaviour of shear waves on the surface, which can be computed with data recorded with the seismometer. In this study, a seismograph data-based computer program in Microsoft Excel was developed for the determination of dynamic soil properties in parallel layered media. It estimates P-S wave velocities and depths of the layers by means of finding out the points of refraction at adjacent layers' interfaces. Consequently dynamic properties of the layers are computed using wave velocity related mathematical equations.
