摘　　要：通过对设计参数的分析，研究了椭圆型双曲抛物面预应力索—拱体系的静力性能。这些参数为索预应力、索垂度、拱矢高、拱竖向抗弯刚度以及索和拱的轴向刚度比。建议一些最优的设计参数和一些有价值的结论供设计工程师参考。The static behavior of a prestresed elliptic hyperbolic cable-arch system is studied by analyzing the design parameters.These are prestress in cables, sag of cables, rise of arches, the vertical flexible stiffness of arches and the axial stiffness ratio between the cable and the arch. Some optimistic design parameters are suggested and some valuable comments are concluded for reference.

关 键 词：预应力索--拱体系 静力性能 双曲抛物面
