摘　　要：结合一座自锚式斜拉—悬索协作体系桥的方案设计,采用了非线性和线性二阶两种方法对活载作用下的结构体系进行了对比计算,讨论了能否用线性二阶的方法替代非线性方法的可行性,对这一体系桥梁的研究与工程设计有一定的参考价值。Combined with a scheme design of self-anchored cable-stayed-suspension cooperative system bridge,the structural system under live load is compared and calculated by means of nonlinear method and linear second order method and the feasibility whether the nonlinear method can be displaced with linear second order method is discussed which provide reference on study and engineering design for this system bridge.
