| Abstract: | According to widening the hollow slab bridge in highway at present,the load transverse distribution coefficient of each plate of the old bridge is calculated in the different way of widening the old bridge,and the effects caused by the changes to the potential bearing capacity of bridge structure are studied.Compare the different transverse load coefficients to determine the optimal scheme and provide theoretical guidance for widening hollow slab bridge in future. |
