Abstract. For typical initial and boundary conditions, a group of general solutions for the generation and dissipation of excess pore water pressure in stone column composite foundation under coupling action of dynamic and static loads have been developed by separation of variables and Green functions to the control differential equations. In the control equation, the pore pressure increasing ratio is expressed as the function of depth and time. A special solution is obtained to zero initial condition and upper boundary pervious, based on an existing dynamic pore pressure calculation model. The numerical example shows that the effect of seepage of the stone column is prominent.
