摘　　要：为促进自锚式协作体系桥体系转换阶段顺利施工,基于无应力状态控制法,研究并提出了具体体系转换方案。通过计算分析可知结构在施工中处于安全范围,且能够精确达到一次设计成桥状态。研究表明无应力状态控制法应用于自锚式协作体系桥体系转换方案中可使施工可行且可控。In order to promote successful construction of self-anchored cable-stayed-suspension bridges,the paper study and propose the specific scheme of the system transformation stage based on unstressed state control method.According to calculation and analysis of the system transformation scheme,it can be seen that the structure can safely approach the designed bridge state.The research showed that the stress-free state control method can be well applied to the system transformation stage of the"cable-stayed to cooperative state",which makes the system transformation stage feasible and controllable.
