混凝土斜拉桥施工线形控制探究

Research on the concretes diagonal cable bridge inquired into construction linear control

临海大桥是一座独塔单索面预应力混凝土斜拉桥。施工周期较长,长悬臂状态混凝土梁及斜拉索受温度影响,对线形影响较大,增加了施工监控的难度,结构线形的控制是施工监控过程中的一项关键内容。

Lin Hai bridge is a cable-stayed bridge with a single pylon and one cable plane. Long construction duration, long cantilever condition of concrete beam and cable affected by temperature affect the linear obviously, which add difficulty of construction monitor control, linear control is a critical content during the construction of the bridge.
