| Abstract: | Based on the monitoring data of the Cha TiaoLing tunnel, located in ShiYan-TianShui Highway, MIDAS, the large-scale finite element software is used. The three-dimensional simulation tunnel excavation process is adopted. And the analysis results and in-situ testing data are compared, which show that after the stress adjustment the tunnel surrounding rock deformation and support structure begin to stabilize after the initial period of support structure construction ; and the arch top sinking and surrounding displacement meet the requirements of moni- toring management standard. |
