摘要
以十堰至天水高速公路茶条岭隧道现场的监测数据为依据,运用大型有限元软件MIDAS,采用三维模型模拟隧道开挖过程,并将数值模拟的结果与实测数据的分析结果相对比。分析表明围岩在初期支护施工一段时间后,经过应力调整,其变形和支护结构受力趋于稳定,拱顶下沉和周边位移满足监控管理标准规定。
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.
