The support design of beam supporting construction of high pier and multi-span continuous beam;
高墩多跨连续梁梁式支架法施工的支架设计
2.
Simple method for establishing the accurate influence line of multi-span continuous beam;
确定多跨连续梁精确影响线的简便方法
3.
Two calculation methods of multi-span continuous beam are introduced.
介绍了多跨连续梁结构的两种计算方法,并对弹性方法和塑性方法进行了分析比较,通过对一三跨等跨连续梁进行的列表分析,得出使用塑性方法比弹性方法计算偏于安全的结论,建议应根据不同的情况使用不同的计算方法,以确保计算结果的合理性。
3) large-span continuous box beam
大跨度连续箱梁
1.
Combined with the construction practice of some a large-span continuous box beam bridge,from the evaluation of connective model,materials,construction technology and connective effects,the paper proposed its treatment methods for reference.
大跨度连续箱梁桥加宽是交通发展所面临的新问题,目前国内新旧桥结构连接尚无成熟的解决方案,特别是在高等级公路改扩建工程要求结构连接施工在不封闭交通的情况下,考虑到新旧结构的不均匀沉降及混凝土收缩、徐变差异等因素,新旧桥梁采用了上部结构不连接而直接做桥面铺装,这样很容易使桥面铺装开裂,影响行车舒适性和桥面外观。
5) continuous box-beam bridge with large span
大跨连续箱梁桥
1.
Reasons analysis and countermeasures for cracks in belly board of continuous box-beam bridge with large span
大跨连续箱梁桥腹板裂缝设计成因分析及对策
6) multi-span continuous bridges
多跨连续梁桥
1.
Based on the key dynamic characteristics of multi-span continuous bridges,a simplified analytical model was adopted to study the effects of traveling waves.
根据多跨连续梁桥的主要结构特点,提出了地震行波效应分析的多跨连续梁桥分析模型。
2.
