摘　　要：为了探究武汉4号线拟建地铁工程盾构施工对地表及周围建筑物沉降的安全性影响,选取某工程地质剖面研究对地表沉降的影响,并特选取该地铁盾构工程埋深较浅处的邻近建筑物进行研究。采用三维数值模拟软件进行实体化建模。并根据相关规范编制安全性判读软件,将所得结果导入后得出结论:盾构施工对建筑物的影响在规范允许范围内。In order to explore the security implications of the proposed subway project shield construction of Wuhan Line 4 on the deposition surface and the surrounding buildings,an engineering geological profile is selected to study its impact on surface subsidence and also specially the surrounding building of the shallow place for the metro shield construction is selected for research.The three-dimensional numerical simulation software is used for physical modeling.The safety interpretation software is compiled based on relevant regulations and the results show that the impacts of shield construction are in the allowable range of specifications.
