摘要：

摘要：预应力锚索在岩土工程加固中广泛应用，通常采用锚索测力计对锚索的有效预应力进行长期监测，利用锚索测力计的测值准确计算锚索的实际荷载尤为关键。对锚索测力计现有数据修正方法进行探讨，同时结合大量的工程实测数据，提出了在不改变仪器自身系数的情况下采用多元回归分析法对锚索测力计数据进行修正的方法。实际应用结果表明，此方法的计算结果精度较高，能够反映结构物的真实运行情况。

Abstract:

Abstract:Prestress anchor cable is wide used in geotechnical reinforcement. Anchor cable dynamometer is used for effective prestress force longterm measurement. Existing anchor cable dynamometer data correction method was discussed. Incorporated with large quantity of measured data, the application of multipleregressionbased anchor cable dynamometer data correction method was stated. The result of practical application examined the accuracy of this method, and it is able to reflect the real operation condition. 
