摘要
按照《超声回弹综合法检测混凝土强度技术规程》(CECS02:2005)要求,采用超声回弹综合法对隧道衬砌混凝土抗压强度进行检测,同时在相同测区采用回弹法、钻芯取样法进行对应比较,通过实际应用,表明超声回弹综合法在隧道衬砌混凝土强度检测中具有较高的准确性,能够满足检测要求,同时分析了该方法在检测隧道衬砌混凝土强度中产生的误差原因及检测过程需要注意事项。
According to 〈 Technical specification for detecting strength of concrete by ultrasonic - rebound combined method 〉 （CECS02：2005） , in this paper the tunnel lining concrete compressive strength is detected with the uhrasonic - rebound combined method, and in the same area the rebound method and core sampling method are used to make comparison. The practical engineering application indicates that ultrasonic - rebound combined method in tunnel lining concrete strength testing can satisfy the detection requirements with high accuracy. In addition,this paper analyzes the cause of human errors in the detection of tunnel lining concrete strength and the notice of the detection process.
