斜拉—悬吊协作体系桥力学特性及其经济性能研究

Mechanics characteristics and economic performances study for cable stayed suspension bridges

斜拉悬吊协作体系桥在软土地基、强台风区等条件下能够突出其优越性。通过该体系与斜拉桥、悬索桥的对比研究及其自身参数变化分析，给出其力学特性和经济性能，为这种桥型的设计和跨世纪跨海工程方案选取提供参考依据。

Cable stayed suspension system is very suitable for the natural condition such as soft soil foundation,violent typhoon and so on. The mechanics characteristics and economic performances of the cable stayed suspension bridges are presented through the parameter analysis and comparative study.The results can provide reference for the 21st century project of strait crossing.
