计算运营期

将按照桥涵规范计算得到的运营期混凝土斜拉桥收缩徐变影响的理论值与实测值进行对比分析，验证规范中收缩徐变计算模型是否可以用于实际大跨度混凝土斜拉桥的计算分析中。

This thesis compared the academic calculation of shrinkage and creep based on design code with long time health monitoring data , verified the shrinkage and creep models in design code are adopted in analysis of actual long-span concrete cable-stayed bridges .

对于运营期，利用道路建设项目的国民经济评价方法计算直接经济效益，再进行投入产出表改进，计算运营期的投入产出乘数，并且提出了计算高速公路运营期总产出的方法。

While for operation period , it calculates the direct economic benefits by national evaluation of road-building project , and calculates the multiplier of operation by improved the Input-Output table . Further more , it proposes the method of calculating total output in operation period .
