摘要
在非洲某国要建设一座大跨度条形钢结构煤罩棚,高度56m,单跨跨度162m,长约420m,在设计阶段对罩棚的施工方案进行了多方案比选。提出了3个可行方案,从安全、工期控制、成本控制等方面比较了各方案的优缺点,从而提出将移动脚手架方案作为最优的推荐方案。设计所需的施工荷载以及现场施工设计均基于该方案。
A stockyard cover shed featured of oversized span, height of which is 56 m, span 162 m, length 420 m, will be built in an African country. We carried multi-scheme comparison for the stockyard cover shed construction scheme in the design phase, proposed three types of construction schemes, and compared the advantages and disadvantages of each scheme from the safety, schedule control, cost control, and etc. The results show that the movable scaffold scheme is the best scheme. The con-struction load and site construction design required for design are prepared according to the recommended scheme.
