地铁盾构机改造技术研究与实践

Research and Practice of Subway Shield Machine Transformation Technology

结合武汉某地铁盾构机扩径改造实例,对比分析新制法、包壳法2种盾构机的扩径方法,通过对改造工期、改造成本、改造后适应性、改造性能、设备使用情况等方面进行对比分析,为后续盾构机扩径改造方法的选取提供参考。

Combined with the example of shield machine diameter expansion reconstruction of a subway in Wuhan,the two shield machine diameter expansion methods of new manufacturing method and cladding method are compared and analyzed.Through the comparative analysis of reconstruction duration,reconstruction cost,adaptability after reconstruction,reconstruction performance and equipment application,it provides a reference for the selection of subsequent shield machine diameter expansion reconstruction methods.
