DESIGN FOR PRESTRESSED STEEL CONVEYER BRIDGE IN DUSHI COAL PREPARATION PLANT

本文重点介绍洗选厂输煤栈桥采用轻型围护结构和以高强度钢绞线作为预应力钢结构五阶段设计、施工、测试和分析。该设计具有省钢、垂直挠度和水平位移小等优点。对于任何大跨度超静定结构的设计,均可借鉴。

This paper emphatically introduces the five stage design, the construction, the test and the analysisof the conveyer bridge of Dushi Coal Preparation Plant using the light covering material andprestressed steel structure, in which high strength strand is used. It has many advantages, e. g. lighterweight, smaller deflection in vertical direction and movement in horizontal direction, etc, it can be usedin design with any long span and statically indeterminate structure.
