APPLICATION OF EARTH CUTTING AND UNDERPINNING TO RECTIFYING DEVIATION AND REINFORCEMENT OF A UNSAFE BUILDING WITH UNEVEN FOUNDATION

应用托换纠偏技术 ,对倾斜建筑物基础沉降多的一侧采用锚杆静压桩方法控制其继续沉降 ,在沉降量少的一侧采用水平掏土法直接从基底掏土迫其沉降回倾 ,在限沉与促沉之间的中部过渡段采用垂直掏土法解除地基应力调整基础均衡沉降。通过几种方法的综合应用 。

By comprehensively applying the earth cutting and underpinning technology including anchor pile control, horizontal earth cutting and vertical earth cutting, a unsafe building has been rectified and reinforced successfully.
