摘要
轨道交通运营因施工原因停运将产生巨大的负面影响。因此需要对新建轨道交通工程下穿既有线路的施工进行分析研究,采取近乎苛刻的安全技术措施,既要保证既有线路的安全运营,又要保证新线安全施工。为避免盾构法下穿既有车站的不利影响,在工程实施前利用有限元计算及模型进行分析、评估,慎重考虑设计、施工及运营对既有地下车站的不利影响,以确保车站结构的安全。对类似工程施工具有较好的参考价值。
The suspension of rail transit operations due to construction reasons will have a huge negative impact.Therefore,it is necessary to analyze and study the construction of new rail transit projects crossing existing lines,and adopt almost strict safety technical measures to ensure both the safe operation of existing lines and the safe construction of new lines.In order to avoid the adverse effects of shield tunneling on existing underground stations,finite element calculation and model were used for analysis and evaluation before the project implementation,and the adverse effects of design,construction and operation on existing underground stations were carefully considered to ensure the safety of station structure.It has good reference value for similar engineering construction.
