The construction of the bridge began in oct 1999 , and the closing up of the steel tube was in dec 2000 . during that period , i learned and analyzed the current construction methods fairly comprehensively , and collected the construction technique data of the cfst arch bridges having been built . based on this , aided by the simulation of construction procedure using finite element program , i proposed the operation program to make the steel tube segment be located at one time , and the scheme of dividing rooms to segment pouring 大桥于99年10月开工， 2000年12月主桥钢管合龙，在此期间，本人就目前钢管混凝土拱桥的施工方法进行了较全面的了解和分析，搜集了此类已建桥梁的施工技术资料，在此基础上，又借助有限元程序对施工过程模拟计算的支持，提出了在梅溪河大桥悬臂安装过程中，钢管节段一次就位的操作程序和钢管混凝土分仓灌筑的方案，并为施工单位采纳应用。
