摘要
对施加预应力阶段引起工形梁侧弯的原因进行分析,并针对其各影响因素明确侧弯防治措施,同时,对已形成侧弯的工形梁提出处理方案,优化施工工艺,减小吊装阶段引起的侧弯量,可为工形梁的侧弯控制提供参考。
The causes of I-beam lateral bending during applying prestressed stage, and the prevention measures are determined as far as the influence factors are concerned. At the same time, the treatment scheme is proposed towards the I-beam having formed and the construction technique is optimized so as to moderate the lateral bending during the hoist stage. It can provide reference for the lateral bending control of I-beam.
