1引言从受力上分析,复合载体相当于等效扩展基础,该技术的理论为侧限约束下的土体密实,即在入土一定深度下,通过柱锤的势能冲切土层形成孔洞,并迅速填料作为介质进行夯实,反复进行,挤压土体中的水和气,实现土体的最优密实,即地面土体不隆起、邻桩不破坏,形成扩展基础,实现力的? 1 Introduction From the force analysis, the composite carrier is equivalent to the equivalent extension of the foundation, the theory of this technology is confined to the soil under the confinement constraints, that is, a certain depth into the soil, through the potential of the column hammer punching soil to form holes, And quickly filled as a medium to rammed, repeated, squeezing the water and gas soil, soil to achieve the best density, that is, the soil does not land uplift, adjacent pile does not destroy the formation of an extension of the foundation, the realization of force?
