Abstract

Abstract: Based on the analysis of the reason of the collapse in top area of a double-archde tunnel,FEM means is taken to study the bad effect of collapse loads and some other facotrs on the secondary lining,then some good advices are suggested for tunnel design and construct

Key words: double-arched tunnel, collapse, FEM means, collapse loads, secondary lining

摘要： 笔者在对一双连拱隧道洞顶坍方原因分析的基础上，借助有限元手段分析了此种坍方产生的坍方荷载等不利因素对隧道已施工的二次衬砌结构可能的各种不利影响，据此对连拱隧道的施工、设计等提出了一些有益的建议.
