In the process of cantilever construction of the Longtan River Bridge ,the WZP-035 thermally sensitive electric resistence, as measured points of temperature, was buried into two segments of box-girder,and the temperature field of box-girder concrete was observed for three days. The observation shows that the temperature distribution of concrete box along the height of box-girder is non-linear under solar radiation. The tested temperature and the temperature difference are given a regression analysis using the least square method. Concrete box-girder temperature mo...
