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. 
