摘要
介绍了小沙湾黄河桥主塔施工过程中,塔梁由同步施工改为异步施工,为防止塔肢应力过大导致混凝土开裂,对施工过程中横撑位置、数量以及横撑主动力进行重新设计。
In the construction processing of the Xiaoshawan Yellow river bridge, the construction way is changed from synchronous to asynchronous, In order to prevent the tower is too much stress to concrete cracking, it need to re-design the braces＇ position, numbers and active force.
