真空预压方法在广州南沙地区软基处理中的应用及效果分析

摘要

In this paper a brief introduction on the principle of vacuum preloading,combined with the Guangzhou Nansha site treatment works instance,the vacuum preloading Soft Ground surface subsidence,layered deposition,the vacuum degree of the field test,through the monitoring data in the analysis above mayout：the degree of consolidation of soft soil in the process can reach more than 80%;vacuum load is applied and the vacuum degree can reach 85kPa;use of the vacuum preloading method to deal with the soft soil of the region is successful,and worth learning.%对真空预压原理进行了简要介绍,结合广州南沙某场地处理工程实例,对真空预压处理软基的过程进行了地面沉降、分层沉降、真空度等现场测试,通过分析以上监测数据得出：在处理过程中软土固结度可以达到80%以上;抽真空可以一次全荷载施加且真空度可以达到85 kPa;运用真空预压法处理本地区软土地基是成功的。
