dead load on bridge

By contrasting curved bridge and straight bridge, influence of dead load and prestressing force on the stress in cantilever casting period of curved Bridges is analyzed.

通过曲线箱梁桥与直线箱梁桥的对比，模拟计算并着重分析了施工阶段自重、预应力等因素对曲线箱梁桥悬浇时应力的影响。

The influences of dead weight of structure, temporary load, structural stiffness, creep and shrinkage in concrete effect on finished dead state of hybrid girder cable-stayed bridge were analysed.

以广州东沙大桥独塔边跨带辅助墩的混合梁双索面斜拉桥为例，采用对比分析的方法，定量分析结构自重、临时荷载、结构刚度、混凝土收缩徐变这些因素对混合梁斜拉桥成桥状态的影响。
