(中建鋼構有限公司，廣州 510600)［摘要］大跨度鋼結構場館跨度大，結構受力復雜，卸載施工難度大。以福州海峽奧林匹克體育中心主體育場為例，對大跨度鋼結構的卸載技術進行研究。采用砂箱卸載裝置、分級不等值的卸載方法，通過施工卸載模擬計算，合理地分配分級卸載值，很好地解決了大跨度鋼結構卸載施工難點。［關鍵詞］大跨度; 支撐; 鋼結構; 卸載技術中圖分類號：TU393.3 文獻標識碼：A 文章編號：1002-848X(2014)22-0056-04Study and application of uninstall technology for large-span steel structuresLiu Ben, Xie Renbin, Zhong Guangjian, Yi Yong（China Construction Steel Structure Co., Ltd., Guangzhou 510600, China）Abstract: Large-span steel structure stadium has the characteristic of complex force and difficult uninstall construction. Take the main stadium of Fuzhou Strait Olympic Sports Center for example to research the uninstall technology for large-span steel structure stadium. By using sandbox uninstall device, hierarchical un-equivalent uninstall and construction uninstall simulation calculation, the hierarchical uninstall value was allocated reasonably so that the problem of uninstall construction for large-span steel structure was solved efficiently.Keywords:large-span; support; seel structure; uninstall technology作者簡介：劉奔，工程師，Email: liuex@foxmail.com。
