| Abstract: | The secondary bending moment from three-dimension prestressing is firstly proposed to calculate the prestress in the Caohe aqueduct of Middle Route Project of S - N water diversion. The calculation of the secondary bending moment and it＇s the impact on the structure of the aqueduct body is discussed with the design examples in the Caohe aqueduct in this paper. The experience summarized in this paper can offer help and reference in calculating three-dimension prestressing in the large aqueduct. |
