| 摘 要： | 结合太湖某水上别墅群高承台桩基加固纠倾工程实例，分析了建筑物倾斜的原因，介绍贴桩加桩的桩基加固技术，提出了堆载静压与桩周扰动相结合的桩基迫降纠倾方法，实测资料表明：提出的桩基加固纠倾技术有效，证实了本工程在桩顶荷载分配及单桩沉降计算中，上部结构的刚性假定是符合工程实际的。

| Abstract: | According to reinforcing and adjusting of several incline villas with pile foundation building in Taihu Lake, based on the study of design, constructing and a long period of settlement monitoring, the reason of the villas incline is analyzed; and how to driven new reinforced pile press close to pile already existed, and fasten them together, is studied. A new method for incline pile foundation adjusting is put forward, which increase pile settlement through disturbing around the pile under the load of the structure. Monitoring settlements indicate that the method put forward is effective and economic, and also prove that when calculating settlement and load of each pile, assuming structure and foundation as rigid accords with the fact. |
