| Abstract: | Longtan River Bridge,which the main span is 200m and the main pier is 178m,is a long span continuous rigid frame bridge.Temperature field of box-pier and box-girder due to solar radiation was measured,regression analysis of the temperature difference using the least square method,and the fitting curve of vertical and transverse nonlinear temperature difference distribution of box-pier and box-girder are obtained in this paper. |
