| Abstract: | The lattice Boltzmann approach is the concrete application of cellular automaton in some specific fields. The dynamic model, simple and completely discreted in time and space, is built according to some basic characteristics of motion on microscopic scale. The average model conforms to macroscopic differential equation. Considering that the models, which are constructed by the lattice Boltzmann approach in microscopic field, originate from molecular motion theory, some merits of molecular dynamics are kept, such as distinct physical graph, simple border processing, absolutely paralled and so on. This paper mainly discusses modeling seismic wave propagation by using lattice Boltzmann method on two-dimensional square lattice media and analyzing the calculation results. According to simulation results, lattice Boltzmann approach has wide potentiality in seismic forward. Further investigation will bring an innovation to devoloping seismic prospecting. |
