10、prestressed-concrete continuous box beam bridge under the action of vertical prestressing, then draw a comparison with the present design method, finally point out major factors in craze of the ventral shield. The analysis shows that we can not design the sizes of vertical pre-stressing in ventral shield according to the present bridge design norm. It takes on important engineering significance for preventing and curing craze in concrete case beam bridge and supervising the design for concrete case beam bridge, and suppli
