| 摘 要： | 箱梁分析常采用空间分析和平面杆系分析2种方法。以陕西杏沟桥为例,将空间分析、平面杆系分析与荷载试验得到的结果进行对比分析,提出采用有限元计算剪力滞效应和偏载效应的具体方法,对不同的计算方法给桥梁设计和安全性评估带来的影响进行阐述,为桥梁设计和安全性评估提供一定的参考意见。

| Abstract: | Spatial analysis and plane link system analysis methods are two most often used box girder analysis methods.Taking Xinggou Bridge in Shanxi as example,this paper carries out comparison analysis to results obtained respectively from spatial analysis,plane link system analysis and load test,and suggestes detailed method for calculating shearing force hysteresis and imbalance load effect by limited elements.It describes the influence to bridge design and safety evaluation by different calculation methods,and provides certain references for bridge design and safety evaluation. |
