摘要
高速公路、铁路的大量修建将会引起很多的路线交叉问题,其中关于后建工程施工对已有高填方路堤的影响值得关注,但目前的研究成果较少。结合某高速公路互通主线桥18#墩右幅承台基坑紧邻京沪铁路的工程实例,利用基坑开挖过程中周围土体变形的监测数据以及有限元的反演分析,对基坑开挖引起高填方路基的变形程度、变形范围以及钢板桩的受力特点从力学机理上进行了探讨,得出了一些有益的结论,可为类似工程的设计、施工提供借鉴。
With the development of expressway and railway, there are more line crossings, which would influence the safety of high- filling embankment. However, few research results can be found now. According to monitored data from one foundation-ditch besides railway during construction and the reversion results from FEM, the paper analyzes the deformation magnitude of pavement and mechanical feature of piling beams in terms of mechanics mechanism.Finally, some conclusions can be gotten for the design and construction for similar engineering.
