大跨径连续刚构桥梁建设中的混合修正施工技术

The Construction Technology of Mixed Correction in the Construction of Long Span Continuous Rigid Frame Bridge

自适应施工控制是推动桥梁工程顺利开展的关键所在,以有限元模型最为关键,需做好修正匹配工作。基于此,论文引入基础参数与经验参数相融合的修正方式,提升桥梁抗弯刚度变形的适应能力,得到合适模拟计算值,保障各工况预测值的可行性。

Adaptive construction control is the key to promote the smooth development of bridge engineering,and the finite element model is the most important one,which needs to be corrected and matched.Based on this,the paper introduces the correction method of the combination of basic parameters and empirical parameters to improve the adaptability of the bending stiffness deformation of the bridge,get the appropriate simulation calculation value,and ensure the feasibility of the prediction value of each working condition.
