大跨径弯连续刚构桥内力分析

利用空间有限元模拟弯连续刚构桥施工阶段所受的各种荷载，通过积分得到各截面内力，并与直桥内力进行对比，得到了一些有意义的结论，为同类型桥梁的内力分析提供一定的参考和借鉴。

The internal force analyses of long span curve continuous rigid frame bridge

Utilizing space finite element to simulate force loaded in construction stage of curve continuous rigid frame bridge, acquiring the internal force of all sections by integration and comparing with the internal force of Straight bridge, this paper obtains some meaningful conclusions and hopes to give some reference when analyses the internal force of the bridge of the same type.
