| 摘 要： | 为了研究围岩等级及埋深对高地温隧道围岩稳定性的影响，以红河州建（个）元高速公路尼格隧道为工程背景，采用现场测试、正交试验及数值模拟相结合的方法，探讨围岩等级、埋深及温度对隧道围岩稳定的敏感性。研究结果表明:隧道拱顶沉降量随围岩等级及埋深的升高而增加，而隧道拱顶沉降量随围岩温度的增加呈先减小后增加的趋势，影响隧道拱顶沉降因素主次顺序为围岩等级、埋深及温度。将数值模拟与现场监测结果对比分析，验证数值模拟的可靠性及准确性。研究结果可为类似高地温隧道设计和施工提供参考。

| Abstract: | In order to investigate the influence of surrounding rock grade and buried depth on the stability of surrounding rock of high ground temperature tunnel,taking the Nige tunnel of Jianshui-Gejiu-Yuanyang highway in Honghe Stateas the engineering background,the sensitivities of the surrounding rock grade,burial depth and temperature on the stability of the tunnel surrounding rock were discussed by using the combined methods of field test,orthogonal test and numerical simulation.The results showed that the settlement of tunnel vault increased with the surrounding rock grade and buried depth,and the settlement of the tunnel vault tended to decrease first and then increase with the increase of the surrounding rock temperature.The main order of factors affecting the settlement of the tunnel vault was the surrounding rock grade,buried depth and temperature.The numerical simulation results were compared and analyzed with the field monitoring results to verify the reliability and accuracy of the numerical simulation.The research results can provide reference for the design and construction of similar high ground temperature tunnels. |
