摘　　要：索—拱体系是索与拱杂交而成的一种新型大跨度屋盖结构,可以充分发挥各自的特点,而且相互限制了彼此的弱点。比单一索的形状稳定性好,比单一拱的整体稳定性好。本文采用能量变分原理对索—拱体系的静力与动力特性分析进行了阐述,并列举有算例说明其应用。Cable - arch system is a kind of large span roof structure combined with cable and arch. This kind of system could sufficiently develop the respective advantage,and restrict the weakness of each Other. The shape stability is better than the cable system, and the integral stability is better than the arch system. In this paper, the static and dynamic characteristic analysis of cable - arch system is discussed, and solved by the energy variation principle. Finally, a numerical example is shown for reference in designing.
