摘　　要：大荷载煤仓因为地基土承载力不够而产生不均匀沉降和倾斜,需要进行加固和纠偏处理。复合注浆法综合利用注浆的加固和抬升效应,进行地基加固和构筑物沉降控制。以大荷载煤仓地基加固为例,对注浆设计与施工进行了介绍,实现了提高地基承载力和降低沉降差的目的。A coal bunker with large loads is easy to appear uneven settlement and tilt because of lack of ground bearing capacity. The foundation needs to be reinforced and the coal bunker needs to be rectified for use. The composite grouting method can reinforce the foundation and control the sedimentation of structures by utilizing the compaction and jacking effects of grouting. Taking a large load bunker foundation’ s reinforcement for example, the paper introduced the design and construction of the composite grouting method to improve the bearing capacity and reduce differential settlement.
