【摘要】 PVA-ECC桥面连接板是指PVA-ECC应用于简支梁桥的两跨或多跨桥在跨间桥面横向连接缝处的连接板。文中分析了桥面连接板的内力和变形量,研究结果表明:PVA-ECC材料桥面连接板受力性能和变形量满足公路规范要求,连接板开裂后裂缝密而均匀,优于普通混凝土桥面连接板。更多还原

【Abstract】 PVA-ECC link slab of bridge deck is the section which located at the transverse connection joint of two spans or several spans of simple beam bridge.This paper analyzed the internal forces and deformations of link slab.The results show that the mechanical behaviors and deformations of PVA-ECC link slab meet requirements of highway standard.The cracks of the link slab are dense and uniform,better than the common concrete link slab.更多还原
