惠济河大桥悬灌梁段冬歇期受力分析及安全控制方案研究

摘要

根据平楡高速惠济河大桥悬灌梁段冬歇期的实际情况,对大悬臂状态下的稳定性进行分析,对冬歇期主粱挠度变化及应力理论进行了计算,并制订了冬歇期的安全防护控制方案,确保悬灌梁段安全过冬。%In accordance with the practical condition of the cantilever-concreting section of the Huiji River Bridge on the Pingyao-Yushe Highway in the winter break,the article analyzes the stability with the big cantilevers,calculates the deflection change of the girder in the winter break along with the stress theory,and makes the safety protection control scheme,to ensure the safety of the cantilever-concreting section in the winter break.
