摘　　要：结合珠海某软基工程,采用快速真空预压结合强夯法进行软基处理。现场试验结果表明,加固后软土物理力学性质明显得到改良,软土强度得到较大提高,地基承载力试验结果满足设计要求,地基加固效果良好,对类似工程具有一定的指导意义。Combined with an engineering of soft foundation in Zhuhai, a new method with rapid vacuum preloading and dynamic consolidation was adopted to treat the soft ground. Field test results show that, physico-mechanical properties of the soft soil are improved greatly after being consolidated, the shear strength of the soft soil is also improved greatly, the result of loading test meets the design requirements, the foundation reinforcement effect was good, had a certain guiding significance for similar projects.
