摘要
讨论了盾构法隧道管片厚度大小对其本身内力变形以及接头转角等受力性能的影响；针对上海地铁某区间隧道所取用的管片厚度，从强度、抗裂、防水、耐久性等几方面探讨了减薄现有管片厚度的可能性。
At first, the effects of segment thickness of shield tunnelling on the lining behavior, such ac internal force, deformation and radial joint rotation etc. are discussed in this paper. Then, as far as the segment thickness of Shanghai subway tunnel is concerned, a study is given on the feasibility of reducing the segment thickness in view of strength, crack resistance, waterproofing and durability etc..
