摘要
为了确保预应力混凝土箱形桥梁的运营刚度满足设计要求,采用有限差分数值计算方法,模拟施工过程,分析混凝土浇筑温度场的变化规律,并探讨了温度场对结构的影响,提出施工控制标准和控制技术,以便确定综合施工工法和温度应力应变的大小。
In order to ensure the operating rigidity of prestress concrete short sectional pier can satisfy designing needs, limited dividing calculation is adopted to simtdate the constructing process and analyze the changing regular of concrete pouring temperature court. It also discusses temperature court's effect on structure, and brings forward the constructing control standard and control skill, so as to fix the integrated constructing methods and the temperature stress changes.
