摘要
基于高墩大跨连续刚构桥的特点和野三河大桥施工时需要调整合龙方案的实际情况,运用有限元分析软件,计算比较了不同合龙方案的结构受力情况,探讨了不同的合龙温度对结构产生的影响。根据计算结果,提出了大桥合龙方案,为顺利合龙提供了指导。
On the basis of the characteristics of long span continuous rigid frame bridge with high piers and the actual situation that the Yesanhe River Bridge construction closure scheme needs to be modified, applying finite element analysis software, the different force conditions of the bridge which applied different closure schemes are calculated and compared, the effects of different closure temperature on the structure are discussed. Based on the calculation,the closure scheme of bridge is proposed and the guiding advices for the successful closure of bridge are provided.
