| Abstract: | Based on the beam construction of Yangtze River Bridge in Qingcaobei, Fuling, construction stand treatment, construction technique and sur-vey control are adopted to analyze deformation control of long-span and large-tonnage beam construction. Thus beam construction can meet construction requirements and construction quality can be ensured. It can offer some references for similar construction. |
