摘　　要：连云港金港湾某堆场地基主要由深厚淤泥质软土构成,采用真空联合堆载预压方式对其软基进行处理。结果表明采用该工艺处理效果明显,避免了单纯堆载预压方法由于加载过大带来的地基不稳定问题,提高了软土地基强度,99 d即达到要求,加快了工程进度。The foundation of Jingangwan storage yard in Lianyungang is constituted of deep muddy clay. The method of vacuum combined surcharge preloading was adapted to improve the soft foundation. The result shows that this technique has obvious effect in treatment, avoided instability of foundation due to overload by preloading method, improved the strength of soft foundation, and expedited the speed of construction that the consolidation of soft foundation can meet the requirement in ninety-nine days.
