| Abstract: | This paper expatiates the basic theory of correction method for finite element model based on quasi-static generalized influence line and applies it to static load test of Southern Approach Bridge of Changshou Yangtze River Bridge successfully. The result of research shows that the simulated and predicted value matches the measured value better after simulation analysis for static load test of Southern Approach Bridge of Changshou Yangtze River Bridge by means of the modified finite element model, showing the feasibility of this method when applied in static load test. |
