盾构隧道计算模型在近接施工中的运用简述

Application Review of the Calculation Model of Shield Tunnel in Adjacent Construction

简要阐述了基本的隧道衬砌设计模型类别,介绍了关于盾构近接施工与近接(既有)盾构施工的多种数值建模方式与应用状况,以及以壳-弹簧模型等可以考虑空间效应及接头非线性的三维数值模型。最后,对搜集到的资料进行总结并展望地层-结构模型在盾构近接施工影响分析中的应用前景。

This paper briely describes the basic types oftunnel lining design models,introduces a variety ofnumerical modeling methods and applications for shield proximity construction and proximity(existing)shield construction,as well as three-dimensional numerical models such as shell-spring model that can take into account spatial effects and joint nonlinearity.Finally,the collected data are summarized and the application prospect of the strata-structure model in the impact analysis of shield proximity construction is forecasted.
