以苏州地铁盾构隧道为计算原型,对设计中的关键参数进行敏感性分析,讨论设计方法、地质参数及结构参数对管片设计的影响,以及管片在水土分算与水土合算条件下受力性能的差异,并对苏州地铁盾构管片设计提出合理建议。

英文摘要：

This paper performs sensitivity analysis on some key design parameters based on Suzhou metro shield tunneling. The influence of the design method,geological parameters and structural parameters on the design of segments is studied; the differences in the behavior of segments are investigated when the water and soil loads on the segments are calculated separately and when the loads are considered simultaneously. This paper also puts forward some reasonable proposals for the design of segments of Suzhou metro.
