| 摘 要： | 本文研究了大跨度深埋黄土隧洞在其它条件不变的前提下, 全断面开挖时黄土的变形破坏规律和衬砌中内力的分布规律, 指出了它们存在本质区别的原因在于不同的开挖方式, 揭示了开挖的本质, 分析了内力合理分布的条件。

| Abstract: | Deformation-failure regularity of loess and force distrubition regularity in lining of large-span deep buried loess tunnel under the other constant conditions along the whole profile during typical step excavation are studied. After revealing their excavation effects, the authors indicate the difference between these regularities are caused by the different excavation pattern, and anlyze the rational force distrubition regularity. |
