摘　　要：针对堆场深厚软土地基处理时传统真空预压法体现的耗时、耗电和施工不便等问题,进行新型直连式真空预压法在堆场深厚软土地基处理中的应用研究。采用现场试验分析施工工艺中存在的问题并提出改进措施,同时结合监测和检测数据分析地基处理的效果,提出新型真空预压技术处理后的场地完全能满足设计要求,确定了后期大面积处理时的排水板类型和间距,节能效益明显,为类似地区的地基处理提供了很好的参考。In view of the problems of wasting time, electricity and construction inconvenience for the convenient vacuum preloading in the foundation treatment of yard＇s deep soft soil are obvious now, we study the application of yard deep soft soil to the yard＇s deep-seated soil foundation treatment. On the basis of field test, we analyze the problems during construction and propose the improvement measures. Besides this, we also analyze the effect of foundation treatment based on the monitoring and testing data. The conclusions are drawn that the soil properties after treatment could satisfy the design requirement completely, which is useful to confirm the type of drain board and spacing, and the energy efficiency is obvious, which could provide reference for the foundation treatment in similar area.
