摘要
文章按照《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大伙房水库输水工程隧道二次衬砌混凝土抗压强度进行检测,同时在相同测区采用钻芯取样法进行对应比较。通过工程实际应用,表明超声回弹综合法在隧道二次衬砌混凝土强度检测中具有较好的保证率,能够满足检测要求。同时本文分析了该方法在检测中影响相对误差的因素。
Based on the technical specification for detecting strength of concrete by ultrasonic-rebound combined method,the paper adopts the ultrasonic-rebound combined method to test the concrete compressive strength for the tunnel secondary lining of water conveyance project of Dahuofang reservoir,also adopts the drilling sample method to compare in the same test area.Through the practical engineering application,the ultrasonic-rebound combined method has the better guarantee rate and meets the test demand in the concrete compressive strength.The paper analyzes the influnce factors of relative error by using the method in the test.
