| Abstract: | According to construction practice experience,it uses the design concept of prestressed zero moment in the auxiliary shipping channel bridge of one bridge under construction.Based on the calculation of structural internal force of original design,it compares the traditional engineering control measures with the design measure of zero moment,and puts forward proposes for controlling long-term deflection,which can provide reference for bridge engineers. |
