| 摘 要： | 以定西隧道为背景，利用有限元软件进行模拟。通过监控量测获得典型断面围岩的变化规律，并将数值模拟和现场量测结果进行对比分析，得到隧道在开挖扰动后初期支护的受力状态，给出隧道初期支护的优化参数，研究将对该类地区黄土隧道的初期支护提供建议和方法。

| Abstract: | Taking the Dingxi tunnel as the background, deformation rules of its typical cross-section's surrounding loess are studied by using the finite-element software; meanwhile, by field monitoring; then the results of numerical simulation are compared with field measurement in order to get the state of stress which brought to the optimal parameters of initial support after excavation. Based on the above, some advices and techniques for initial support in the similar region, are put forward. |
