摘　　要：真空预压因其良好的处理效果,广泛应用于软土地基的处理。本文结合上海某软土地基处理工程实例,对真空预压法在软土地基础处理过程中的施工工艺、关键技术进行阐述分析,并提出相关改进措施;结合相关监测结果,对真空预压处理后的地基加固效果进行分析和研究。研究结果表明,真空预压后的地基土固结效果明显,在指定的时间内达到了目标沉降值,满足了设计要求。本课题为真空预压法在软基处理中的应用提供了一定的参考价值。Vacuum preloading is widely used in soft soil treatment because of its good treatment effect.Based on the example of a soft soil foundation treatment project in Shanghai,the construction technology and key technologies of vacuum preloading method in the process of soft soil foundation treatment are expounded and analyzed,and relevant improvement measures are proposed.Combined with the monitoring results,the consolidation effect of the ground after vacuum preloading treatment is analyzed and studied.The results show that the effect of vacuum preloading is obvious,and the target settlement value can be achieved in a short time.This paper provides some reference value for the application of vacuum preloading method in soft foundation treatment.
