| 摘 要： | 基于圆形隧道围岩稳定性的粘弹性力学分析基础之上，通过对粘弹性本构模型的改进，引用对数函数来描述岩石蠕变的本构模型．通过等代圆半径算法，把一般深埋隧道简化为圆形隧道，使其适应一般断面形状的隧道，最后给出了铁山坪隧道工程算例。

| Abstract: | Based on viscoelastic mechanical analysis of the stability of surrounding rock in circular tunnel, through the improvement to viscoelastic constrictive model, this paper cites a logarithmic function to describe the constrictive model of rock creep. Through calculation of radius for equivalent circle, a general tunnel is simplified into a circular one in order that the laws in the paper apply not only to circular tunnel, but also any other tunnel. An engineering example about Tie Shan Ping tunnel is also given, which conies to the conclusion that theoretic value is quite matched to measured one. It has a certain referential meaning to either the stability of surrounding rock in deep tunnels or the check about supporting design. |
