BRIDGE MONITORING AND SAFETY EVALUATION METHOD USING A VIBRATION TECHNIQUE
First Claim
Patent Images
1. A bridge monitoring and safety evaluation method, comprising the steps of:
- a) obtaining the basic data of a bridge and using the basic data to make a bridge structural model and then performing a vibration test on the bridge structural model by means of using a vibration source to pass over the bridge at a predetermined speed and recording the vibration conditions of the bridge at specific locations; and
b) using the test result of said vibration test to correct the bridge structural model and to establish judgment criteria and to further establish the relationship between the bridge structure safety and bridge pier vibration frequency for estimating a bridge warning threshold value.

Abstract
The invention relates bridge structure safety evaluation technology by means of combining vibration measuring and structural model analysis techniques for bridge erosion evaluation and pre-warning monitoring applications. This technology can also be applied for long-term bridge structure monitoring and safety evaluation as well as judgment and evaluation of rail structure abnormality.
