Abstract
The author studies stability of a structure (platform) on a pile foundation using physical modeling. Disturbing force is applied by a pendulum generating seismic impulse vibrations. The data on measured displacements of two points on the platform surface are used to find the platform incline under varied number of blows, blow energy, distance to the blow point and the platform weight.
