疏桩复合地基在结构加固纠偏中的应用

Application of the Composite Foundation with Sparsely Spaced Columns in the Building Differential Settlement Corrections

详细介绍了疏桩复合地基的基本理论和受力机理,论述了概念设计在疏桩复合地基设计中的应用,讨论了疏桩复合地基承载力的综合确定。通过工程实例,分析论证了既有结构的倾斜原因及加固方案,同时阐述了疏桩复合地基在既有结构加固、纠偏中的具体应用,分析了疏桩复合地基在迫降纠偏中应用的可靠性,指出概念设计可以成功地应用于疏桩复合地基对既有结构进行加固纠偏的工程中,并取得较好的加固效果,应用疏桩复合地基对既有结构进行迫降纠偏,是安全可靠的。

This paper introduces the basic theory and stress mechanism of the composite foundation with sparsely spaced columns and the application of this method in the correction of a building suffering from the differential settlement.The factors that cause the inclination of the building evaluated and the differential settlement mitigation plan is presented.From the analysis of the axial resistance compressive columns,it is concluded that this method is reliable in the differential settlement mitidations.
