摘　　要：新近发展起来的ＬＢ方法具有并行度高、几何边界易处理等优点．作为用之解决实际问题的尝试，本文建立了能模拟水电站水击的一维ＬＢ模型，给出了基本原理、方法及步骤，并与特征线法进行比较．分析表明ＬＢ方法是有效的，将之引入水电站流场计算具有可能性，值得探讨．Water hammer is simulated by the recently developed Lattice Boltzmann method which is fully paralleled and can deal with complex geometries. Basic principles, computing algorithm and comparisons between results of the LB and the method of characteristics are presented. It is shown that the LB method is a feasible choice to simulate hydraulic problems in engineering.
