Deviation rectifying method for overlying building settlement caused by subway construction at soft soil stratum
The invention discloses a deviation rectifying method for overlying building settlement caused by subway construction at soft soil stratum. The deviation rectifying method comprises the steps of measurement before construction, hole position arrangement, raft-shaped composite foundation construction, composite pile construction, reinforcing and lifting, and grout supplementing and reinforcing. The method has the beneficial effects that a novel structural body combining a raft-shaped composite foundation reinforcement body and composite pile foundation reinforcement is formed, and the strength, the impermeability and the stability of the structure are greatly improved, so that the purpose of reinforcing the stratum is achieved; and meanwhile, on the premise that the safety of an upper structure is not affected, the position with the large local settlement amount can be appropriately lifted, the settlement difference is reduced, the inclination amount is appropriately reduced, the foundation bearing capacity and the overall stability and durability of the foundation are improved, the purpose of improving the bearing capacity of the building foundation is successfully achieved, and the requirement for the foundation bearing capacity and the requirement for durability are met.
本发明公开了一种用于软土地层地铁施工导致上覆建筑物沉降的纠偏方法，包括工前测量、孔位布置、筏型复合地基施工、复合桩施工、加固抬升、补浆加固。本发明的有益效果是：形成筏型复合地基加固体与复合桩基加固相结合的新的结构体，其强度、抗渗性及稳定性得到大幅提高，从而达到加固地层的目的。同时，在不影响上部结构安全的前提下，局部沉降量较大位置可适量抬升，缩小沉降差，适量减小倾斜量，提高了地基承载力、地基整体稳定性和耐久性，成功解决了建筑地基承载力提升的目的，使其达到地基承载力要求和耐久性要求。
