箱型截面梁桥的结构力学分析

Mechamical Analysis of Sthe Structure on the Bridge of Box－section

用平板壳元素建立了箱型截面梁桥的结构力学分析模型，并对广东惠洲大桥主桥——异型段箱型截面连续梁桥进行了计算。

The elements of plane—shell are used to establish the model for mechamical analy-sis of the structure on the bridge of box—section，The mainpart of thasec large at Huizhou inGuongdong has ben alculated，which is a continual bridge with special—shaped box—section. The result has been applied to the design in practical engineering.
