| 摘 要： | 交通轨道施工环境复杂,周围高层建筑物林立,威胁着建设工程安全施工。因此,加强大型建设项目施工过程中的形变监测有助于施工项目安全开展。本文以水准测量技术为监测手段,对宁波市轨道交通3号线工程进行了形变监测,文章从3个方面进行形变分析。监测结果表明,深层土体位移最大为131.37 mm,支护桩顶部水平位移最大为2 mm,支护桩顶部沉降位移最大为2.1 mm,地表沉降最大为201.4 mm,项目施工开始至结束,未出现报警值情况,说明建设工程整体设计合理,认为该建设工程项目对临近建筑物影响不大,可以安全施工。

| Abstract: | The construction environment of traffic track is complex, and the surrounding high-rise buildings are lined with buildings, which threaten the safe construction of construction projects. Therefore, strengthening the deformation monitoring in the construction process of large-scale construction projects is helpful to the safe development of construction projects. In this paper, the standard measurement technology as the monitoring means, the Ningbo City rail transit line 3 project for deformation monitoring, the article from 3 aspects of deformation analysis. The monitoring results show that the maximum displacement of the deep soil is 131.37 mm, the maximum horizontal displacement of the top of the support ingres is 2 mm, the maximum settlement displacement at the top of the support ingress is 2.1 mm, the surface subsidence is 201.4 mm, the project construction starts to the end, there is no alarm value, indicating that the overall design of the construction project is reasonable. It is considered that the construction project has little impact on adjacent buildings and can be safely constructed. |
