The Responses of Soft Ground Materials Subjected to Dynamic Loading
The responses of saturated soft soil foundation under dynamic loading are analyzed using numerical method.The distributions of pore pressure in space are given,and the variations of pore pressure with time are also discussed.Besides,the distributions of vertical stresses and vertical displacement are also given.Studies show that during the period of dynamic loading,the pore pressure and stress in soil layer grows very fast,and also decreases rapidly in the unloading phase.With the increase of dynamic compaction time,the locations of the maximum values gradually move down.Moreover,the pore pressure and stress gradually decreases with the increase of the distance away from hammer point.On the other hand,the tamping pit in ground surface under dynamic loading has a larger settlement,and furthermore decreases with the increase of depth.
