桥梁缆索体系线型控制的广义索力调整方法

在缆索结构的设计、施工和运营过程中，常碰到调整缆索索力以满足线型要求的问题，说明广义索力调整方法的必要性和实用性。通过计算力学的逆分析原理．建立线型控制的广义索力调整方法，即增广目标函数的内部惩罚函数法。从数学上说明优化算法收敛，并以一钢管混凝土拱桥灌浆前主拱钢管合龙线型控制的实例，对所提出算法的有效性给以论证。

General Adjustment Method of Cable Forces for Line-Style Control of Cable-Bridges

of cable forces to approach a design line-style of a bridge floor usually is involved in design, construction and running of cable-bridges, which makes a general theory of cable forces adjustment necessary and practical. This paper sets up a general theory of cable -forces adjustment for line-style control based on inverse analysis theory of calculation mechanlcs-lnternal penalty function method by constructing a supplementary object function, whose convergence is expounded in mathematics and whose effect is demonstrated by a engineering example, the line-style control of the load-bearing steel arch conjunction before concrete casting for a certain concrete-filled steel tube arch bridge.
