车辆振动对新旧桥拼接混凝土性能的影响

Effect of Vehicle Vibration on Performance of New Bridge Splicing Concrete Engineering

以实际工程为背景,进行新旧桥现场浇注连接段混凝土的力学性能研究。结果表明,受到振动后混凝土的抗压强度有上升趋势,劈裂强度变化不大,钢筋与混凝土的握裹力出现下降,但下降幅度不大。

Taking one engineer as an example, the article studies the concrete mechanical performance of site pouring connection section of new and old bridge. The results show that the compressive strength of concrete after vibration has an upward trend, the cleavage strength changes little, the bond stress of reinforcement and concrete decreases evidently.
