摘要

针对Ⅲ、Ⅳ级围岩，以江西高速公路隧道为背景，采用弹-黏塑性有限单元法分析预测不同类别隧道围岩变形。选取现场Ⅲ、Ⅳ级围岩进行室内剪切流变试验，分析得到Ⅲ、Ⅳ类岩样流变试验曲线与广义Kelvin 模型的流变曲线吻合较好。基于广义Kelvin模型，推导出黏弹性模型复杂应力状态下的应力-应变关系。采用施工过程的黏弹性动态反分析法计算围岩参数，结合反演参数对预测隧道围岩变形进行预测分析。研究成果已应用于实际隧道工程中，指导、修正设计和施工参数，可为安全施工提供合理依据。

Abstract

For Ⅲ

Ⅳ grade rocks

the different deformation types of tunnel surrounding rocks are analyzed and forecasted using the elasto-viscoplastic finite element method based on Jiangxi highway tunnel. First

the Ⅲ

Ⅳ grade rocks are selected

to carry out indoor shear rheological tests and analyze generalized Kelvin rheological test curve and find the flow curves agree well with the model for Ⅲ

Ⅳ grades rock samples. Based on the generalized Kelvin model

viscoelastic model is derived under the stress - strain relationship of complex stress state. Finally

the dynamic viscoelastic back analysis method of the construction process is used to calculate rock parameters

combined with inversion parameters for prediction analysis of tunnel surrounding rock deformation. The research results are applied to the actual tunnel construction to guide and revise design and construction parameters

so as to provide a reasonable basis for safe construction.
