| Abstract: | In order to assess the cracking performance of cross-sea bridge in water freezing-thaw and erosion coupling,through establishment of the Ottosen strength criterion on concrete freeze-thaw and erosion,combined with the characteristics of northern freezing coastal areas and the structure of non-navigable bridge,the crack resistance performance of a few key points on the bottom of concrete pile cap of non-navigational bridge were analysed and assessed.The results show that cracks will occur at the bottom of co... |
