Abstract
A solution of the wave equation for the pile driving analysis by means of the finite difference method is presented in this paper. According to the method of solution presented here, the boundary conditions and the wave equation are differentiated and formed into simultaneous equations, and then the wave equation at the boundaries are solved. This method basically follows the same procedure as an analytical method and thus is able to obtain wave equations that stand good at any point of the pile system. Because of this, as long as the behaviour of pile system can be expressed by the one dimensional wave equation, it is possible to obtain the numerical solutions even though the pile system is complex.
