| Abstract: | In the light of structure design for prestressed drainage aqueduct in middle line project of water transfering from south to north, the finite element method is adopted to analyse local prestressed steel lose efficacy. By way of contrast study for aqueduct stress distribution under different lose efficacy modeling, the maximum lose efficacy modeling of stress for this aqueduct indicated. |
