Abstract:

Xi’an Metro Line No.2 is an a important track traffic network south-north main stem of Xi’an city. For its construction, the key problem is crossing the earth crevasse. In light of the problem mentioned above, the structural design measures and waterproof project of metro section crossing earth crevasse, are described in detail. For the activity of earth crevasse, The structural measure is: "Prevention" and "release" the combination, The structure adapts The deformation of the earth crevasse primarily; The structure cross section expands, reservation distortion space, The structure cross section expansion reservation distortion space, the structure partition addition distortion seam adaptation distorts, the attachment to use the flexible connection, Strengthen the structural strength to resist deformation due to structural damage;Simultaneously adopts Frame plank structure being adjusted, assures the operation security; Waterproofing measures taken in the special way, using a large-strain properties of the new unique Design project of waterproof.

Key words: metro, earth crevasse, waterproof, structural measure
