Analysis of Pile-Soil Interaction by Computer Simulation

In this paper, a numerical model to simulate the interaction of pile-soil based on the one-dimension stress wave theory is established, which can provide the propagating process and reflection characteristics of stress wave under impulsed load in concrete piles. The simulation is carried on about the stress wave in integrated pile and defective pile, which provide all kinds of the propagating characteristics. It can enhance the accuracy of dynamic test. The validity of this approach is verified through the comparison of the measured curve and the simulated curve.
