Optimizing Research on Leading Hole Position in Soft Rock Tunnel Under High Crustal Stress
Author(s): 
Pages: 59-62
Year: Issue:  8
Journal: Railway Construction Technology

Keyword:  高地应力软弱围岩超前导洞应力释放数值模拟;
Abstract: 以兰渝铁路毛羽山隧道为工程背景,利用数值模拟分析研究方法,优化研究超前导洞位于正洞的合理位置.通过建立超前导洞在不同位置的数值模型,从导洞开挖时的围岩变形情况、正洞扩挖后围岩变形情况及应力释放率三方面进行对比分析,研究了超前导洞位置对围岩变形的影响规律,确定了最优的超前导洞位置,以便结合监控量测数据指导高地应力软岩隧道施工.
