某高层住宅楼基础纠偏加固设计及施工监控

摘要

Collapsing due to the improper handling of the foundation,design flaws for wet,resulting in uneven settlement of building foundation,causing the upper structure is inclined,on the basis of theoretical analysis and engineering practice,proposes a rectification of new technologies.Out of soil and using lime piles and steel pipe pile composite pile group composite correction method,a wet base-rise residential buildings collapsing was rectifying and reinforcing.In order to achieve the purpose of building rectification righting.Long-term monitoring results show that after binding construction,correction of the high-rise building reinforcement achieved the desired effect.%针对湿陷性黄土地区由于地基处理不当、设计存在缺陷,造成建筑物地基的不均匀沉降,引起上部结构倾斜,在理论分析及工程实践的基础上,提出了一种纠偏加固的新技术.采用掏土法与钢管桩和石灰桩组合桩群的综合纠偏法,对某湿陷性黄土地区的高层住宅楼基础进行纠偏加固,以达到建筑物纠倾扶正的目的.结合施工后的长期监测结果显示,该高层建筑物的纠偏加固取得了预期效果.
