摘　　要：强夯置换碎石桩法是将碎石回填至夯坑内部,并利用巨大的夯击能量把块名压入土层底部,块石沉底形成桩体,能够形成一个由碎石垫层、桩间土和碎石桩共同构成的复合地基,从而起到加速土体固结,提高土体抗剪强度的作用,以此满足公路建设施工要求.The dynamic tamping replacement gravel pile method is to fill the gravel back into the rammer pit, and press the block stone into the bottom of the soil layer by using the huge tamping energy, and the pile body can be formed by the rock sinking bottom, which can form a gravel cushion layer composed of broken stone hardcore, soils among piles and gravel. The composite foundation can accelerate the consolidation of soil and improve the shear strength of soil, in order to meet the requirements of highway construction.
