摘要
为确定钢管混凝土拱桥灌注后主拱肋的灌注质量,确保桥梁的安全,结合超声波对钢管混凝土检测的原理,对某钢管混凝土拱桥试验模型进行超声波检测,得到钢管混凝土拱桥混凝土灌注后,脱空的普遍规律及对超声波检测混凝土脱空量的验证。
In order to determine the concrete filled steel tube arch bridge after perfusion of the main arch ribs of perfusion quality,ensure the safety of bridge,combined with ultrasonic wave on concrete filled steel tube detection principle,on a steel pipe concrete arch bridge test model for ultrasonic detection of steel pipe concrete arch bridge,get bored concrete,the universal law of void and ultrasonic to detect the concrete void volume validation.
