| 摘 要： | 在岩溶地区隧道建设中,经常遇到溶槽、溶管、溶洞等岩溶地质问题.目前对隧道穿越溶槽时围岩的变形特征及其稳定性研究较少.结合岩溶地区某连拱隧道穿越大型溶槽的施工过程开展岩石力学试验和隧道动态施工力学三维模拟,对连拱隧道围岩位移、应力、塑性区特征进行分析和评价,为岩溶地区连拱隧道围岩稳定性分析和溶槽处治方案设计提供依据.

| Abstract: | Karst geological problems such as karst grooves,karst pipes and karst caves,etc.are often encountered in construction of tunnels in karst area.As of now there are few studies on torsional features and stability of wall rocks when tunnels pass through karst grooves.In combination with construction process of a multi-arch tunnel through large karst grooves in karst area,this paper develops mechanical tests for rocks and 3D mechanical simulations for dynamic construction of tunnels,analyzes and evaluates for d... |
