چکیده:

experimental results to investigate the dynamic behavior and impedance function of foundations resting on a sand layer are presented in this paper . Physical model block vibration tests were carried out in a cubic steel container of size 1.0m×۱٫۰m× ۰٫۸m using foundations in one circular shape. the radius of the circular foundation was 7.5cm.the employed vertical force generator was a B&K vibraiton exciter system driven by a power amplifier. using available sea sand a sandy sample with specific density was prepared and tests werecarried out for footing shape.
