摘要： 为解决存在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差异沉降、甚至主体结构开裂倾斜等问题；采用真空联合覆水预压的方法对某房建项目之深厚软基进行前期处理，并从理论计算及现场施工等方面对该工法应用进行了研究，根据项目进展情况知该工法切实可行，可有效地消除前述相关问题，值得推广应用。

Abstract: It is a common practice for soil improvement methods in residential areas to strengthen only soils under the buildings. Therefore, differential settlement after construction might occur and even result in the cracking and/or tilting of buildings. This paper presents the results of a Vacuum Combined with Water Covered Preloading method for the entire site of a proposed residential development. Both theoretical and practical aspects of this technique are discussed in the paper. It is concluded that this method is successful in minimizing potential differential settlement.
