摘　　要：随着社会经济的发展和科技的进步,桥梁建设在满足功能需求的同时,对美观、环保、经济等方面的要求也越来越高。中跨变截面连续刚构箱梁以其优良的性能和广泛的应用,逐渐成为了现代桥梁建设的重要选择。然而,这种结构在支架设计和施工过程中存在一定的风险,需要对结构稳定性风险进行深入的研究和评估。本文依托徐明高速项目,将针对中跨变截面连续刚构箱梁支架设计风险进行研究。为了降低变截面箱梁支架设计的风险,需要进行充分的风险评估和管理。这包括进行详细的地质勘察和基础设计,以确保支架的稳定性和承载能力;合理选择施工设备和材料,确保施工质量和安全性;采取恰当的安全措施,保障施工人员的生命安全;以及进行严格的施工监控和管理,确保施工进度和质量符合要求。With the development of social economy and technological progress,bridge construction not only meets functional re⁃quirements,but also has increasingly high requirements for aesthetics,environmental protection,economy,and other aspects.The mid span variable cross-section continuous rigid frame box girder has gradually become an important choice for modern bridge construction due to its excellent performance and wide application.However,there are certain risks in the design and construction process of this structure,and in-depth research and evaluation of structural stability risks are needed.This article relies on the Xuming Expressway project to study the design risks of mid span variable cross-section continuous rigid frame box girder supports.In order to reduce the risk of variable cross-section box girder support design,sufficient risk assessment and management are needed.This includes conducting detailed geological surveys and foundation designs to ensure the stabili⁃ty and load-bearing capacity of the supports;Reasonably select construction equipment and materials to ensure construction quality and safety;Take appropriate safety measures to ensure the safety of construction personnel;And carry out strict con⁃struction monitoring and management to ensure that the construction progress and quality meet the requirements.
