摘　　要：在该倾斜建筑物的加固纠偏工程中,首先,通过设置托换防沉桩限制沉降较大一侧的变形,然后,在沉降较小一侧进行水平掏土纠偏,并根据沉降观测资料及时调整掏土孔的间距、长度和方位,掏土纠偏完成后,及时利用注浆法对掏土孔进行封填处理。沉降观测结果表明,该倾斜建筑物的加固纠偏取得了预期效果。Some measures must be done quickly in the inclined-building correction, the first thing is to construct some foundation- underpinning-pile at the side with more settlement, and the second is to carry out digging-out-soil hole at other side. Its parameters can be adjusted according to the settlement supervision, such as spacing, length and direction. After correction working, the digging-out-soil hole must be fulled by the use of cement liquid. The supervision result shows that the design and construction of the inclined building correction is successful.
