摘　　要：以某注浆加固工程为例,研究了分层注浆加固技术在处理既有建筑物不均匀沉降问题中的应用。结果显示,分层注浆可以有效的提高地基承载力,减小建筑物的沉降,加固效果显著。The paper gave an example of a grouting reinforcement project, which studied the application of stratified grouting reinforcement technique in dealing with the uneven settlement problem of the existing buildings. The results show that the stratified grouting can effectively improve the bearing capacity of the foundation and decrease the settlement of buildings and get a significant reinforcement effect.
