Aiming At the Problem of the Cable Force Evaluation of the Self-Anchored Concrete Suspension Bridge after Curing, This Paper Evaluates the Relationship between the Cable Force Before and after Maintenance by Testing the Frequency of the Boom and Calculating the Cable Force Using the String Vibration Method; the Software Calculates the Frequency of the Boom and Compares It with the Actual Measured Frequency on the Site to Determine the Accuracy of the String Vibration Method to Measure the Cable Force of the Boom. Through this Test, It Provides a Reliable and Effective Cable Force Test Program.
