| 摘 要： | 在城市已运营桥梁附近实施新的项目,已经是城市建设中越来越容易碰到的课题,将对桥梁结构的结构受力和安全运营产生长期的影响1]。以实际工程为依托,采用ABAQUS有限元软件进行分析,建立承台-桩-土耦合模型,研究大面积堆载对杨浦大桥主墩的影响,涉及沉降、水平位移等方面。并分析其变形规律,得到相应的结论。其成果希望能为同类工程起到一定的参考作用。

| Abstract: | A new project implemented near an operational bridge in city has been an increasing easy subject to encounter in the urban construction,and will has the long-term influence on the structural stress and safe operation of bridge structure.Relying on a practical project,ABAQUS finite element software is used to carry out its analysis.The base slab-pile-soil coupling model is established to study the influence of large-scale preloading on the main pier of Yangpu Bridge involving the aspects of settlement and horizontal displacement.The deformation rule is analyzed.The relative conclusion is obtained.The results are expected to be the reference for the similar projects. |
