摘　　要：随着我国现代化建设进一步深入,为满足未来体育赛事承办要求和人民日益增长的体育文化需求,体育设施场馆扩改建逐渐成为一种趋势,既有结构的改造施工已成为施工领域的重要组成部分.与通常的新结构施工不同,改造施工并非一个结构从无到有、逐渐成形的过程,而主要是对现役结构荷载工况、支承条件和自身构件等的局部改变.因此,在改造施工过程中,主要受力构件的应力、变形等变化规律难以通过施工理论计算来准确模拟,在施工过程中及时监测结构关键部位的应力、变形情况显得更为重要.本文基于服役20年的黄龙体育中心主体育场既有挑篷结构,通过对改造施工过程中结构关键部位的应力、变形进行监测与分析,探究结构在改造施工过程中应力与变形的变化规律,对类似既有体育场馆改造施工具有一定参考价值.With further development of China's modernization and people's growing demand for sports events and sports culture,the expansion and reconstruction of sports facilities and venues have gradually become a trend,and the reconstruction of existing structures has become an important part of the construction field.Different from the usual construction of a new structure,reconstruction is not a process in which the structure emerges from nothing and gradually takes shape,but mainly involves a partial change of the load condition,support condition,and components of the existing structure.Therefore,it is difficult to accurately simulate the stress and deformation changes of the main stressed components during the reconstruction process.It is more important to monitor the stress and deformation of key parts of the structure in time during the construction process.Based on the existing canopy structure of the main stadium of the Huanglong Sports Center,which has been in service for 20 years,this paper monitors and analyzes the stress and deformation of key parts of the structure during reconstruction process,and explores the varitation law of the stress and deformation of the structure during the reconstruction process,which can be of reference for reconstruction of similar existing gymnasiums.
