    摘要
  • 摘要: 箱涵顶进置换管幕工法是中国新创的城市隧道暗挖方法，施工过程中土体变形情况是检验施工工法成功的关键。针对箱涵顶进置换管幕工法的模型试验过程，设计了基于BOTDR分布式光纤传感技术的土体变形传感器并在室内进行了性能测试，同时根据该工法的施工特点建立了三维变形监测网络。在试验结果和监测数据的基础上，分析了工具管幕推进和箱涵置换工具管幕过程中土体的变形特性，验证了该技术的可行性。试验研究成果对于分布式光纤土体变形监测和完善该施工工法的智能监测系统具有重要意义。
    Abstract: The construction method of a box culvert being pushed to replace two pipe roofs is initiated as a city tunnel excavation method in China. This method is complex, and soil deformation is the key factor to test whether the construction method is successful or not and to guarantee the tunnel safety. The soil deformation sensors are introduced based on the distributed fiber sensing technology, their performances are tested in the laboratory, and a three-dimensional deformation monitoring network is designed according to the model tests. The test results and the monitoring data are analyzed. The soil deformation characteristics during the pipe-roofs pushing and box culvert replacement are summarized. This study will play an important role in perfecting the intelligent monitoring system, improving this construction method and analyzing the deformation of engineering soils.
