改进型真空预压法在沿海吹填淤泥地基处理中的应用

Improved Vacuum Preloading Method in Costal Dredged Mucky Soils

基于实际工程分析了针对新近吹填淤泥的改进型真空预压法的加固效果。通过施工过程的分析,总结了施工工艺及技术控制措施。对沉降、孔压、真空度、十字板剪切强度等监测数据进行了分析。结果表明该方法能够对沿海吹填淤泥软基进行快速处理,施工方便,加固效果能够满足设计要求。

This paper presents a case history of using an improved vacuum preloading method for the improvement of dredged mucky soils.The construction procedures and the key technical aspects of this improved method are summarized.The monitored data include：settlement,pore water pressure,degree of vacuum,and the vane shear undrained shear strength.The results indicate that this improved method can provide a fast and simple construction soil improvement tool for the coastal dredged mucky soils and the result of this method is satisfactory.
