Abstract: In this paper, the (3+1) dimensional KP-Boussinesq and BKP-Boussinesq equations are studied by using the bifurcation theory of planar dynamical systems and Hamilton energy functions. All the branches and phase diagrams of the traveling wave solutions of these two equations are obtained, and the exact parameter expressions and parameter conditions of all the traveling wave solutions are also calculated. In the paper, the traveling wave solutions of these two equations are obtained, including solitary wave solutions, periodic wave solutions and kink wave solutions.
