摘　　要：浅表层快速加固技术是基于真空预压原理针对新吹填淤泥等超软弱土快速加固的一种新技术。依托惠州港荃湾港区软基处理工程,通过现场试验研究不同排水板间距对浅表层快速加固效果的影响,研究加固过程中膜下真空度、地表沉降和孔隙水压力的变化规律,对惠州荃湾吹填淤泥加固前、后土体的物理力学性质、强度及地基承载力进行分析。The shallow rapid reinforcement technology based on the vacuum preloading principle is a new technology of rapid reinforcement technique for the new reclamation silt. Relying on Huizhou Quanwan port soft foundation treatment engineering, we study the influence of different drainage plate spacings on the shallow rapid reinforcement effect by the field test. We also study the rules of the process of strengthening about the vacuity under the membrane and the surface settlement and pore water pressure, and analyze the soil physical and mechanical properties, strength and bearing capacity of foundation before and after the reinforcement.
