摘　　要：振冲挤密加固处理主要通过振冲器的强烈振动使基础颗粒重新排列、孔隙减少,依靠振冲器的水平振动力,把回填的粗集料挤入周边介质并将孔内粗集料压实,从而提高地基承载力。广泛应用在各类土的液化处理、砂土以及湿陷性土等基础的加固处理,水下回填砂砾料基础由于砂砾料颗粒直径大、强度高,振冲挤密难以处理至设计深度,使用较少。The vibro-punching compaction st rengthening treatment mainly makes the foundation particles rearrange and the pores decrease by the strong vibration of the vibrator,and depends on the horizontal vibration force of the vibrator.The backfilled coarse aggregate is squeezed into the surrounding medium and the coarse aggregate in the hole is compacted,thus improving the bearing capacity of the foundation.The vibro-punching compaction strengthening treatment is widely used in all kinds of liquefied soil liquefaction treatment,gravel soil,sand,artificial fll,as well as collapsible soil foundation reinforcement treatment.
