| 摘 要： | 选取对隧道稳定性影响较大的病害之一——空洞作为分析对象,基于辽宁海棠山隧道衬砌后空洞对结构安全影响的模型试验,利用岩土隧道分析有限元软件MIDAS（GTS）进行数值分析,研究空洞在拱肩、边墙、拱脚以及拱底等不同位置对隧道衬砌的力学行为的影响。通过对衬砌轴力和弯矩的分析,得出不同位置的空洞都会影响衬砌结构的安全性能,衬砌...

| Abstract: | By choosing the empty hole,which is one of the diseases having greater impact on the stability of a tunnel,as an analysis object,and based on Liaoning Haitangshan Tunnel's model tests,the numerical analysis is made by using the finite element analysis software MIDAS/GTS so as to study the influence on the tunnel lining's mechanical behaviors of the empty holes in different positions.Through the analyses for the lining's axial force and bending moment,it is obtained that the empty holes in all different posi... |
