采用反拉法预应力检测仪对需要检测的钢绞线逐根进行锚下有效预应力检测，根据检测结果计算出单根、整束和全断面的锚下有效预应力的偏差值是否大于控制要求。锚下有效预应力的检测可通过对有效预应力进行控制和验收评估能够评定其梳束、编束、穿束、调束的工艺水平以及张拉控制水平，做到以有限的检测达到全面控制预应力施工质量。
採用反拉法預應力檢測儀對需要檢測的鋼絞線逐根進行錨下有效預應力檢測，根據檢測結果計算齣單根、整束和全斷麵的錨下有效預應力的偏差值是否大于控製要求。錨下有效預應力的檢測可通過對有效預應力進行控製和驗收評估能夠評定其梳束、編束、穿束、調束的工藝水平以及張拉控製水平，做到以有限的檢測達到全麵控製預應力施工質量。

the effective prestress by anti pull method of steel strand , the need to detect by prestressed anchor tester detection , according to the detection results to calculate the effective prestress , the whole beam deviation of single and whole section un-der the anchor value is greater than the control requirements .Effective detection of prestressed anchor can pass control and ac-ceptance evaluation of effective prestress can assess its comb beam , beam, technological level through beam , beam tuning and tension control level , to achieve limited detection to achieve comprehensive control of prestressed construction quality .
