摘要
结合高过河特大桥13号主墩施工实践,对钢支撑锁定结构体系在高墩施工中的应用进行了探讨,通过对相关设计参数进行计算,从理论上验证了该方案的可行性,并在实际实施中取得了良好效果,实现了桥墩与钢系梁施工平行交叉作业,有效节约了工期,故值得推广。
Combining with the construction practice of No. 13 main pier of Gaoguohe super big bridge, this paper discussed the application of steel support locking structure system in high piers construction, through calculating to relevant design parameters, verified the feasibility of this scheme in theory, gained good results in actual implementation, achieved parallel-cross operation of bridge piers and steel line beam construction, effectively saved time, worthy of promotion.
