| Abstract: | Taking the removing and restoring of the old bridge along Ningbo Rail Transit Line 1 for example,the bridge pier colliding with the shield should be extracted in advance for the shield smooth tunneling in the field of rail transit shield construction.Several key points are introduced covering traffic organization,the key technique for old pile extracting,pipelines relocations,etc.Finally,some important problems are pointed out about the removing & restoring bridge design. |
