摘要
处理因基坑事故造成的工程桩偏位和倾斜具有时间紧、技术难度大的特点。针对温州地区某大厦工程桩发生偏位的情况 ,现场进行了紧急处理 ,对偏位、倾斜工程桩动测确定无断桩后对其降级使用 ,对偏位桩进行静载荷试验确定其真实承载力 ,在基础四周补桩、修改承台设计 ,以及预留进一步补桩的构造措施 ,以确保整个建筑物桩基和基础承台的安全性。
The paper introduces a foundation pit accident in Wenzhou area and the treatment to piles and foundations. The integrality of leaned piles is investigated, the capability of leaned piles is decreased to a rational extent, in-situ test is made to know real capacity of leaned pile, repiling, modifying the foundation design. Structure measure for possibility of future repiling is reserved to e nsure the safety of building. It is proved that the treatment is successful.
