摘要
通过对真空预压法处理软土地基有效加固深度的研究现状分析和工程实例中真空预压表层沉降、分层沉降和孔隙水压力现场监测的分析,找出在真空压力作用下加固效果随时间和深度的变化规律,并总结了该工程真空预压法处理软土地基的有效加固深度,进而提出在南沙地区处理深层软土地基的建议。
Based on the study on effective reinforced depth of soft foundation treated by vacuum preloading method and monitoring results of surface settlement,layered deposition and pore water pressure in field tests on an actual project,the relationship between the effects of reinforced treatment with time and depth are obtained,and the effective reinforced depth of soft foundation treated by the vacuum preloading method of this project is concluded.Some suggestions for treatment of deep soft foundation are proposed in Nansha.
