摘要
为缓解钢-UHPC组合桥面板易开裂的问题,文中设定装配式钢-UHPC组合桥面板,并对其湿接缝轴拉性能进行研究:在试验室中完成试件制备,并应用轴拉实验装置对其性能进行测定分析。实验结果表明,装配式钢-UHPC组合桥面板轴拉性能高于基础施工桥面板与钢-UHPC组合桥面板,可对外界荷载进行平均分配,进一步缓解桥面开裂问题。
This project is to alleviate the steel-UHPC composite deck problem,set the prefabricated steel-UHPC composite deck plate,and its wet joint shaft pulling performance is studied.Test piece preparation was completed in the laboratory,and its properties were determined and analyzed by applying the axis pull experimental device.The experimental results show that the shaft tensile performance of prefabricated steel-UHPC combined bridge deck plate is higher than that of foundation construction bridge deck plate and steel-UHPC combined bridge deck plate,which can distribute the external load evenly and further alleviate the problem of bridge deck cracking.
