英文摘要	Based on the existing design and calculation about grillage supporting structure with pre-stressed anchor bars, the author applies the integral optimization and the local optimization for its optimization and analysis design. In this paper,by taking the unit project cost of main materials of unit length in the supporting structure as the objective function,the layout of anchor bars, the section dimensions of members, the main bars and stirrups as the design variables,and the design and detailing requirements in the present code as the constraints,an optimum mathematical model about the grillage supporting structure with pre-stressed anchors is established. Then the complex method is adopted to search the optimum design. The numerical examples show that the proposed method can obtain the most economical design and this design approach may be used as reference for the similar supporting structure.
