| Abstract: | With the first line of Nanjing metro as background,mechanical behavior of the segmental structure of shield tunnels in the whole construction process and in the stabilized period has been comprehensively studied together with in-situ tests.And finite element numerical simulation analysis based on'beam-spring' model has been adopted at the same time with the obtained results summarized and compared.In consequence,the design principles and methods for the segmental structure of metro shield tunnels in viscous strutum are put forward. |
