摘　　要：采用现场实测与计算机仿真分析相结合的方法,对张弦桁架需悬挂200kN楼盖使用荷载的新型工艺进行了分析,着重阐述吊挂楼盖、悬索张拉及撑杆下料尺寸的确定及施工工艺,最后得到了施工顺序影响整体结构的受力状态、悬索张拉施工过程中,索张力与位移基本呈线性关系等结论。Adopting the method of survey on site combining together with computer emulation, it analyses the new-type craft of the truss string hanging 200kN floor service load, the paper explains emphatically three construction craft of suspending the floor, stretching cables and the sureness of the baiting measurement of strut legs and at last draws some important conclusions such as the construction order influences stress of whole structure, and while stretching construction, the cable tension and the node of the midspan displacement present the linear relations basically.
