摘　　要：一办公楼建于水库岸滩回填地层之上,由于回填处理不当和库区水位季节性变化较大,导致楼房不均匀沉降。利用加固后楼房的反向不均匀沉降,结合钢管微型桩分期和分区施工,成功对楼房进行了纠偏和加固。结合实际工程,介绍使用钢管微型桩对楼房进行基础加固和纠偏的方法,通过观测数据说明钢管微型桩对倾斜楼房进行纠偏加固的效果,期望在处理类似工程问题时起到借鉴作用。An office building is constructed on a backfilled stratum located at the bank of a reservoir. Because of unsuitable ground treatment and great seasonal water level change of the reservoir,the building occurs nonuniform settlement. Making use of the building′s inverted nonuniform settlement caused by reinforcement,combining the micro-steel-piles which are constructed by stages and areas,the rectification of the tilted building has been successfully conducted;and the foundation of the tilted building has been reinforced. On the basis of engineering practice ,a method for reinforcement of building foundation and rectification of tilted building with micro-steel-piles is introduced. The effects of the reinforcement of the building foundation and rectification of the tilted building with micro-steel-piles are also illuminated using the observed data. It is expected that this can provide references for similar projects.
