摘　　要：采用有限元动力分析方法,建立二维简化模型对强夯加固机理、位移、应变及应力特性进行了分析;研究了10次锤击和变形控制对最佳锤击次数和强夯有效加固范围。结果表明:最佳锤击次数为6次,有效加固宽度约为2倍夯锤直径,深度约为2.5倍夯锤直径。2D simplified model was established to analyze the consolidation mechanism,displacement,strain and stress characteristics by dynamic finite element analysis. The optimal hammering numbers and effective reinforced area were studied by 10 times hammering and deformation control. It is indicated that optimal hammering number is 6. The effective reinforced areas are 2 times of the rammer diameter in width and 2. 5 times in depth.
