| Abstract: | The middle roof of Yinchuan Railway Station building is three-span arch shell with prestressed fair-faced concrete.The spatial changing-surface shell has complex structural form.The effect of fair-faced concrete is obtained by making arch shell model in advance at field,using on-site construction of three-dimensional measuring technology,dividing reasonable construction segments and reasonable process.A good construction management efficiency is achieved. |
