Mechanic Character of Reinforced Concrete Tunnel Bridge

采用组合板单元对多种地道桥结构进行有限元空间分析 ,通过大量的计算分析提出了斜交地道桥简化为正交地道桥的计算模型 。

In this paper,space analysis of structures of various tunnel bridge is made by using combined plate element. According to the numeri cal results, the calculation model in which skew tunnel bridges can be simplified to the orthogonal tunnel bridges has been propo sed. It which can simplify the works of the design.
