Abstract


In this thesis, using a combination of wind tunnel tests and CFD calculations library segment spit on the southern border line second-tier bridge the the wind wall structure parameters of its wind load parameters , trains , bridges and other wind load parameters of the system , first CFD computational analysis, comparative analysis of wind structure parameters , according to the analysis results to determine a more reasonable wind wall structure parameters , and then through the wind tunnel tests , wind parameters chosen to verify the wind wall , if necessary, further adjusted accordingly. This paper studies the content and results include: the Institute used ( 1 ) to determine the typical bridge site at the wind characteristics and wind parameters ( 2) through the analysis and testing of the system , the the wind wall structure to obtain a more optimized the reasonable structure type , reasonable ventilation rate and wind wall height . (3) obtained through the analysis and testing of the system , trains , bridges and wind wall structure of aerodynamic parameters , wind wall is set to provide a reference for the design . (4) characteristics obtained the set wind wall train operating at different speeds when the wind load parameters , through the analysis of the system , and train operations through wholly reviews . (5) analysis to calculate the dynamic characteristics of the bridge wind wall , and its features reviews trains wind under . ( 6) proposed southern border lines in windy weather ( Turpan to Korla paragraph second line ) on the train the operators speed limit value and speed limit . (7) Computational analysis of the strength of the wind wall structure .
