摘要:
采用ABAQUS有限元分析软件,以北京地铁7号线区间隧道作为工程背景,考虑到衬砌与土体之间的相互作用,建立了地基土-隧道体系的整体有限元模型,针对不同断层类型工况下,隧道结构在不同埋深下的反应进行了系统分析.研究结果表明:隧道结构处于弹性阶段时,在规范规定的取值范围内适当地减小隧道埋深可以减轻结构的反应;在较大断层位错作用下,隧道结构产生的损伤区域长度,以及出现损伤最严重的位置不受埋深的影响;在逆断层下,隧道埋深为10m时,结构震害程度最为严重;在正断层下,隧道埋深为8m时,结构震害程度最为严重;在走滑断层下,隧道埋置越深结构受到的震害程度越严重.
Abstract:
Using finite element analysis software ABAQUS and taking the range of Beijing Metro Iine 7 as engineering background, the integrated finite element model of ground soil-tunnel was established by considering lining-soil interaction. The response of tunnel structure with different embedment depth was analyzed systematically under different fault types conditions. The results show that the response of tunnel is reduced with decrease of tunnel depth properly in the stipulated range of codes under the elastic stage; structural damage region length and the most severe damage location is not influenced by embedment depth under larger fault dislocation;structural earthquake damage is the most serious when embedment depth of tunnel is 10m under reversr fault; structural earthquake damage is the most serious when buried depth of tunnel is 8m under normal fault; The degree of structural damage increases with the increase of embedment depth of tunnel under strike-slip fault.
