摘要
本文以应力分析为基础,提出了确定土质隧道围岩坍塌(滑)范围的有限元追踪分析方法,以进行旨在克服目前各种计算方法确定松动压力缺陷的研讨。
In this paper,the problem of the collapse range of earthtunnel is studied by tracking analysis with the finite element method,which is based on stress analysis.The aim of this paper is to discusssome calculating methods by which the loosening pressure acted on tunnelis decided at the moment.
