项目摘要
Construction of long (to 60km), large (>10m) diameter tunnels for rail, road and hydraulic networks is a $30 billion industry worldwide. Many of these tunnels traverse highly foliated or laminated ground conditions. Other tunnels, in hard rocks, experience induced anisotropy (spalling). These conditions, combined with anisotropic stresses can generate high anomalous loads and moments in liners and arch support. Canadian companies are involved in many of these overseas projects and a number of projects encounter similar conditions in Canada (Niagara-Beck tunnel, La Ronde Mine, Highway tunnels in B.C). This proposal combines a synthesis of international experience, behavioural testing and state-of-the-art numerical analysis, to better constrain ground response predictions and optimize support design in order to provide competitive benefit to Canadian tunnelling and mine development. The research plan involves 7 new graduate theses (4 MSc, 3 PhD), plus the completion of 3 thesis projects already in progress, organized into 5 project themes:
为铁路、公路和水工网络建设长(60公里)、大(10米)直径的隧道是一个价值300亿美元的全球产业。许多这样的隧道穿过高度叶状或层压的地面条件。在坚硬岩石中的其他隧道则经历了诱导的各向异性(剥落)。这些条件,再加上各向异性应力,会在衬垫和拱支撑中产生很高的异常载荷和力矩。加拿大公司参与了许多海外项目,许多项目在加拿大遇到了类似的情况(Niagara-Beck隧道,La Ronde矿山,卑诗省的公路隧道)。该提案综合了国际经验、行为测试和最先进的数值分析,以更好地约束地面反应预测和优化支持设计,从而为加拿大的隧道和矿山开发提供竞争优势。研究计划涉及7篇新的研究生论文(4篇硕士论文,3篇博士论文),加上完成3个正在进行的论文项目,分为5个项目主题:
