大跨度张弦梁施工全过程管控实践与思考 ——以恩施州民族体育运动中心项目为例

Full-process Control Practice and Reflection on Long-span Beam String Structures Construction——A Case Study of Enshi Prefecture Ethnic Sports Center Project

摘要:

大跨度张弦梁结构因其优异的跨越能力与空间表现力，在现代体育场馆建设中应用广泛。其施工过程技术复杂、风险高，对监理管控提出严峻挑战。本文恩施州民族体育运动中心项目74.6米跨度张弦梁成功实施为背景，从监理方视角出发，系统阐述了从地面拼装、地面初步张拉、高空吊装到高空二次张拉全过程的质量、进度、安全管控要点、实施策略与经验总结，为类似工程提供借鉴。

Abstract:

Long-span beam string structures are widely used in the construction of modern stadiums due to their excellent spanning capacity and spatial expressiveness. Their construction process is technically complex and high-risk, posing severe challenges to supervision and control. Based on the successful implementation of the 74.6-meter-span beam string structure in the Enshi Prefecture Ethnic Sports Center project, this paper systematically expounds the key points, implementation strategies and experience summaries of quality, schedule and safety control throughout the whole process—from ground assembly, initial ground tensioning, high-altitude hoisting to secondary high-altitude tensioning—from the perspective of the supervision party, providing reference for similar projects.
