摘　　要：以最小弯曲应变能法为理论基础,引入优化理论,运用通用有限元软件ANSYS与自主研发的集成优化软件系统SiPESC.OPT,得到一组成桥索力.算例表明,该方法既能快速得出结果,又能在精度上满足工程实际需要,适用范围广,并可以考虑不同成桥目标与约束,值得进一步研究和探讨.Taking the minimum bending strain energy method as the theoretical basis and introducing the theory of optimization, the optimized hanger tensions can be obtained with the help of the general finite element software ANSYS and the self-developed integrated optimization software system SiPESC. OPT. The example shows that this method which with wide range of application can rapidly obtain results whose precision can meet the engineering real needs, and it also can consider the different kinds of objectives for the finished bridge and the different kinds of constraints. This method is worthy of further study and discussion.
