斜拉桥和自锚式悬索桥相互协作,形成一种新型的协作体系,该体系适合于大跨径桥梁。本文以大连庄河建设大桥为背景,介绍了该体系桥梁的设计构思,分析了该体系静力、动力特性,并阐述了吊索疲劳问题,为斜拉—悬索协作体系的研究提供参考依据。
Cable-stayed bridges and self-anchored suspension bridges work together to form a new type of collaboration system that is suitable for long-span bridges. Based on the background of Dalian Zhuanghe Bridge, this paper introduces the design concept of the system bridge, analyzes the static and dynamic characteristics of the system, expounds the fatigue problem of the sling, and provides a reference for the research on the cable-stayed-cable collaboration system .
