Abstract: (5601 Views)
Evaluation of ground response is one of the most important issues that should be considered in seismic geotechnical engineering field. Alongside the earthquake path associated to regional soil, generally earth movement in places with soft soil is greater than the movement in places with harder soil. This paper is focused to identify local soil condition of Ardekan city which influences on earthquake wave shaking. Therefore after drilling boreholes, implementing geotechnical investigations and down hole geophysical tests, the soil layer characteristics and thicknesses have been obtained. Then shear wave velocity along with soil density have been determined. With using these data it is developed a shaking geotechnical models for different city regions. Finally the ground movement parameters have been determined by the available data obtained such as density, wave velocity along with using the equivalent linear method employing EERA program. This work was prepared for the return period of 75, 475 and2475 years. It is found that northwest region of city has the most amplification in comparison to other regions.
