在城际轨道建设中，将深基坑周边邻近建筑物影响降到最低，是设计及施工必须研究的课题。为了解决深基坑开挖过程中邻近建筑物的安全问题，结合莞惠城际轨道GZH-5标工程实例，采用有限元模拟分析方法及该工程大量监测数据，通过建筑物加固前后变形情况对比，深入地研究超深基坑开挖对其邻近建筑物的影响及控制。主要得出以下结论：1）与基坑的距离关系，是影响开挖期间建筑物变形规律的主要因素；2）模型能有效预测莞惠城际GZH-5标施工过程中10层居民楼变形终值超过控制值，可为制定加固措施提供参考；3）该施工加固方案能有效控制10层建筑物的变形与沉降，合理可行。

During the construction of inter-city rail transit projects,the influence of the construction of deep foundation pits on the adjacent buildings has to be minimized.In this article,the influence of the construction of the deep founda-tion pit of GZH-5 bid section of Dongguan-Huizhou inter-city rail transit project on the adjacent buildings and its control technologies are studied,and comparison and contrast is made between the displacement of adjacent buildings before grouting reinforcement and that after grouting reinforcement,and between the finite element analysis result and the moni-toring result.Conclusions drawn are as follows:1 )The distance between the foundation pit and the adjacent buildings is the main factor that influences the displacement of the adjacent buildings;2 )The finite element calculation model can effectively predict the displacement of the adjacent buildings during the construction of the foundation pit and thus the prediction result can provide reference for the determination of the building reinforcement measures;3 )The grouting re-inforcement measures taken are reasonable and feasible for the control of the displacement of adjacent buildings.
