摘要
为确定城市明挖隧道的合理断面型式,采用有限元计算方法,对不同型式隧道断面的受力特性、材料用量及经济性进行了对比分析研究,提出了常见的30 m宽隧道的推荐断面型式,为类似工程的断面选择提供了定量的依据,具有重要意义。
In order to determine the reasonable section type of urban open cut tunnel,the stress characteristics,material consumption and economy of different types of tunnel section are compared and analyzed by using the finite element method.The recommended section type of common 30 m wide tunnel is put forward,which provides quantitative basis for the selection of fracture surface of similar projects,which is of great significance.
