摘　　要：壁后注浆是盾构隧道施工的关键环节,而同步注浆是为了减少盾构隧道施工对土体扰动而采取的壁后注浆方法之一,是盾构隧道施工的重要施工工艺,对土体变形有着显著的影响。从理论方法研究、数值计算、模型试验和实测分析等几个方面分别阐述了同步注浆对土体变形影响问题的研究现状,同时,结合工程实际总结分析了一些减小同步注浆引起的地表变形的措施,最后分析了盾构同步注浆对土体变形影响还存在的一些问题和可能的研究方向。Back-wall grouting is the key link in shield tunnel constructions, and synchronous grouting is one of the back-wall grouting methods to reduce the disturbance of shield tunnel construction to the soil. It is an important technology of shield tunnel constructions, and has a significant influence on the soil deformation. The paper elaborates the research status of synchronous grouting effect on soil deformation problems from the theoretical method, numerical calculation, model tests, and measured analysis. Some summaries in combination with the engineering practice to reduce ground deformation caused by synchronous grouting measures were made, finally it analyzes the problems and the possible research direction of the shield synchronous grouting effect on deformation of soil.
