摘要
采用RS-ST01D非金属超声波测试仪检测环形钢筋混凝土电杆的强度和内部缺陷。探讨环形钢筋混凝土电杆裂缝的产生机理,获得超声波测强的拟合方程,并推导出纵向裂缝深度的计算公式。在此基础上,给出一个具体的环形钢筋混凝土电杆强度与裂缝深度的工程检测实例,获得剩余使用寿命的时间。这对类似工程质量检测、健康性能评估和耐久性寿命预测具有一定的参考作用。
The method of ultrasonic tests was employed to investigate the strength and defects in circular rein- forced concrete poles, and mechanism of the crack emerged on the circular reinforced concrete was discussed, whereby acguining the fitted equation of the strength. Then the relevant formulas for the depths of longitudinal circular cracks were derived. Based on this, a specific engineering testing example for strength and the depth of cracks of circular reinforced concrete pole was given, and the residual service life time was obtained. It is great significance for similar engineering in concrete quality detection, health performance assessment and service life prediction.
