AN INVESTIGATION OF THE EFFECTS OF DYNAMIC LOADS ON THE SHEAR STRENGTH OF SOILS

Soils supporting the foundations of structures subjected to vibrating loads often exhibit strength and elastic properties which are considerably different from the properties of the same soil under static conditions. The effects of dynamic loads may include: (1) unacceptable amplitudes of displacement and acceleration of equipment housed in the structure or of the structure itself, (2) propagation of stress waves from the foundation supporting dynamic loads, and (3) reduction of the load-carrying capacity of the soil. The purpose of this investigation was to develop an apparatus which could be used for laboratory investigations of the effects of dynamic stress conditions on the shear strength of a soil. An attempt was also made to determine the effects of static shear stresses, confining pressure, and the amplitude of vibration on the velocity of stress wave propagation in a soil sample.
