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。
For the deep soft foundation of the project in the late use of the main building due to the settlement of the ground settlement caused by the difference between the settlement and even the main structure of the slope cracking and other diseases; Based on the theoretical calculation, on-site construction, construction monitoring, post-mortem inspection and other aspects of the work method analysis, that the vacuum over water pre-pressure treatment of housing projects deep soft foundation can eliminate the differential settlement during the late project operation And other issues. The method to deal with the deep foundation of the project of housing construction can meet the design requirements, and has the advantages of convenient construction and short construction period, and can eliminate the diseases caused by the method of directly using pile foundation, which is worthy of popularization and application.
