| 摘 要： | 针对地下快速路的特点和重庆市地形特征,分析了在重庆市地下快速路中使用双层隧道的优越性,并根据双层隧道边墙受力不利原则提出了两种双层隧道新型结构方案。利用计算软件对两种新型结构相对于传统结构的稳定性和边墙二次衬砌受力进行了分析比较,得出边墙位于中隔板中部的双层隧道结构更加适用于城市地下快速路。

| Abstract: | In view of the characteristics of underground expressway and the Chongqing terrain,the superiorities are expatiated in using the double-deck tunnel in Chongqing underground expressway,and two kinds of new structures are proposed according to the stress state of lateral wall of double-decked tunnel by using the computation software.It is concluded that the lateral wall located in the middle of the median septum of the double-deck tunnel structure is favorable for urban underground expressway,after the comparison of stability analysis and stress state of these two structures and the traditional structure. |
