针对大跨径连续刚构桥的合龙温度控制问题。采用有限元分析软件对大跨径连续刚构桥的不同合龙温度顶推力进行分析计算,得到了不同温度与合龙顶推力的关系,分析结果表明:温度对大跨径连续刚构桥的合龙力影响显著,大于设计合龙温度时,每增长单位摄氏度,最大合龙力呈500kN增加,此研究成果可为实际工程借签和参考。 Aiming at the Closure Temperature Control Problem of Long Span Continuous Rigid Frame Bridge. The finite element analysis software was used to analyze and calculate the different thrusting thrusts of long span continuous rigid frame bridges. The relationship between different temperatures and thrusting thrusts was obtained. The results show that the relationship between temperature and the closing force of long span continuous rigid frame bridges The effect is significant. When the temperature is greater than the design closure temperature, the maximum closing force increases by 500kN for every unit of degree Celsius. This research achievement can be borrowed and referenced for the actual project.
