主 题:Saturated clay Lattice Boltzmann method Consolidation Time-dependent loading
摘 要:The lattice Boltzmann method(LBM)has been widely employed in various areas of practical engineering to solve non-linear problems,due to such advantages as the simplicity of programming and the numerical *** this paper,a new numerical method for onedimensional(1D)consolidation analysis of saturated clay is proposed on the basis of the lattice Boltzmann *** first,the lattice Bhatnagar-Gross-Krook(LBGK)model is used for 1D consolidation problem of saturated clay subjected to time-dependent loading under different types of initial and boundary *** addition,the multiscale Chapman-Enskog expansion is applied to recover mesoscopic lattice Boltzmann equation to macroscopic consolidation *** a result of the numerical simulation for verification,the numerical results are proved to be in good agreement with the analytical solutions available in previous *** the evaluation of convergence and accuracy,it is demonstrated that the proposed method is more accurate and reliable than the finite difference method(FDM)for 1D consolidation analysis of saturated clay.
