摘    要:针对深厚软基的房建项目在后期使用过程中因仅对主体建筑进行地基处理而引起的差异沉降、甚至主体结构开裂倾斜等病害;采用真空联合覆水预压法对某房建项目之深厚软基进行前期处理,并从理论计算、现场施工、施工监测、工后检测等方面对该工法进行分析,认为真空覆水预压法处理房建项目深厚软基可以消除后期项目运行过程中的差异沉降等问题。该工法处理房建项目深厚软基可满足设计要求、施工方便、工期较短、且可消除以往直接采用桩基处理等方法产生的病害、切实可行、值得推广应用。

关 键 词:真空覆水预压  软基处理  设计  施工  监测检测  处理效果

Abstract:A common hazard of the building founded on soft soils is the differential settlement after the completion and even tilt- ing and cracking of the structures. This paper presents a case history of soft soil improvements for a residential building project by using vacuum preloading combined with water surcharging. The design, construction, monitoring and evaluation aspects of this method indicate that this method can effectively minimize the common hazards of building foundations on improved thick soft soils. The vacuum preloading combined with water surcharging method has the advantages of meeting design requirements, easy construction, short construction duration, and cost effective.
Keywords:Vacuum Preloading Combined with Water Surcharging  Soft Soil Improvements  Foundation Design  FoundationConstruction  Monitoring and Testing  Improvement Results
