【Abstract】 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.更多还原
