摘要
针对隧道耐久性存在的问题,给出了隧道设计模型,对底部反力为0、底部反力为顶部荷载的50%、底部反力等于顶部荷载三种情形下的荷载模式进行了分析,并对各种情形下的结构内力进行了比较,得出了一些有益的结论。
According to problems existed in durability of tunnel, it brings forward tunnel designing mode, analyses three kinds of situations including bottom reacting force is 0, bottom reacting force is 50 % of top load, and bottom reacting force equals top load, compares structural inner force under different conditions, brings forward some worthy conclusions.
