摘要
通过对可调胎架底座的合理运用,以及对主要杆件应力应变实时监测并指导卸载,顺利完成了平台桁架大跨度区域的结构卸载工作,解决了传统利用千斤顶整体顶升分级卸载的困难,操作方便,结构加载过程均匀,可防止杆件应力突变,且能够实时监测主要杆件受力情况,能够安全合理地完成整个卸载施工,取得了很好的技术效益和经济效益。
Wide-span structures of platform truss are successfully unloaded and difficulties in traditional integral lifting by jack and unloading in different levels are solved through reasonable application of adjustable assembly jig base, real-time monitoring of stress-strain on main rods and unloading convenient construction and uniform structure loading are realized to prevent abrupt Favorable technical and economic benefits are obtained through real-time monitoring of safe and reasonable unloading construction. guidance. Simple and change of rod stress. forces on main rods,
