| 摘 要： | 东北隧道围岩大部分为粘性土,局部见砂层,部分地段含水量较高,围岩呈软可塑状态,自稳能力差。针对此特点,通过模型试验、室内理论分析和现场试验测试,系统研究比较了几种典型大断面隧道施工方案,选取了适合严寒地区大断面软塑粘土隧道施工的方法,并通过施工实践对隧道施工技术、施工工艺进行了深入研究和探讨,总结了一套严寒地区大断面浅埋软塑粘土隧道快速安全的施工技术。

| Abstract: | Most tunnel surrounding rocks in Northeast of China are composed of clay soil,while some parts are composed of sand layer,some sections are with high water content and the surrounding rock is soft and plastic with poor stable ability.According to these features,through model test,indoor theory analysis and on-site test,the construction schemes for several typical large cross section tunnels are systematically studied and compared,and the construction methods suiting for large cross section soft and plastic ... |
