摘要: 随着城市轨道交通的迅速发展,盾构法施工技术的应用越来越广泛,但在盾构隧道管片计算方法及计算软件的选择应用方面,还没有达成统一。从两种常用的盾构管片计算分析软件——“同济曙光盾构隧道分析软件”与“火炬软件”入手,采用较为合理的计算模型,结合实际工程资料,进行盾构管片结构内力计算分析比较。通过比较分析两种软件的建模方式、考虑的荷载工况及计算结果的异同,提出关于盾构管片计算方法方面的建议,为更合理地选择盾构管片计算软件提供参考。分析结果显示,“同济曙光盾构隧道分析软件”在软件建模、荷载工况设置以及结果分析上都更有优势。

Abstract: With the rapid development of urban rail transit, the shielded tunneling technology is widely used in the construction of rail transit. It has become the primary choice of tunnel construction. However, the generally accepted opinion is not identified in selection of an appropriate analysis method as well as the analysis software for the shielded tunnel segment. In this paper, two different shielded segment analysis software for predicting the internal forces in the shielded segment are compared in a practical project. This paper also presents the appropriate recommendations of the analysis in the shielded segment based on the comparison and analysis of the two different software in modeling methods, the load conditions and the results.
