Building combination loading forced landing deviation rectifying method
The invention relates to the technical field of civil construction, in particular to a building combined loading forced landing deviation rectifying method, which comprises the following steps of: observing the settlement difference of a building, reinforcing a foundation on one side with larger settlement by adopting a high-strength prestressed pile, applying prestress to support and lock the pile, and inhibiting the settlement of the side through the prestressed pile. A pre-stressed anchor cable is adopted to apply pre-stress pull-down to the side, with small settlement amount, of the foundation; meanwhile, by calculating the weight of a heavy object needing to be stacked and loaded, the weight of the heavy object is stacked and loaded on the raft plate on the side, with the small settlement amount, of the foundation, the side, with the small settlement amount, of the foundation is forced to settle downwards, the settlement difference of the building is continuously observed till the settlement amounts of the two sides of the building tend to be consistent, and if little springback exists after the heavy object is unloaded, the weight of the heavy object is calculated. And if not, the pre-stressed anchor cable is locked, the springback amount of the foundation is effectively controlled, and it is ensured that the deviation rectifying result is controllable. And if the deviation correction requirement is met according to the springback condition calculation, the pre-stressed anchor cable can be unloaded in a graded mode, and corresponding observation is conducted to complete deviation correction.
本申请涉及土木建设技术领域，尤其涉及一种建筑组合加载迫降纠偏方法，通过观测建筑的沉降差，采用高强预应力桩对沉降较大一侧基础进行加固，并施加预应力上托并锁桩，通过预应力桩抑制该侧的沉降。采用预应力锚索对基础沉降量小的一侧施加预应力下拉；同时，利用计算所需堆载的重物的重量，在基础沉降量小的一侧的筏板上堆载前述重物压重，迫使基础沉降量小的一侧向下沉降，不断观测建筑的沉降差直至建筑物两侧沉降量趋于一致，在卸载压重物后若有少量回弹，则对预应力锚索进行锁定，有效控制基础回弹量，确保纠偏成果可控。若根据回弹情况推算满足纠偏要求，则可将所述预应力锚索分级卸载并进行对应观测完成纠偏。
