摘要：In the calculation of the superstructure of PC cast-in-place continuous beam bridge, the optimum degree of structural stress has a great influence on the performance of the structure. In this paper, the stress optimization process of the superstructure of PC cast-in-place continuous girder bridge is described in detail, and the parameter θ of stress optimization index is put forward, and the validity of the parameter applied in engineering example is studied.
