| 摘 要： | 在对既有钢筋混凝土拱桥进行有限元分析的基础上,在满足荷载试验效率的前提下,首先确定荷载试验工况、车辆荷载及布置、试验分级及测试项目等关键内容,然后对其进行现场荷载试验。通过现场加载试验来对其承载能力进行评定,进一步明确钢筋混凝土拱桥荷载试验的步骤和重点。

Load Experiment of Existing Long Span Steel Reinforced Concrete Arch Bridge |
| |
| Abstract: | Based on the finite element analysis of the existing steel reinforced concrete arch bridge,and under the premise of satisfying the load experimental effect,the article firstly defines the key contents of load experimental cases,vehicle load and arrangement,experimental grades and testing contents,and then introduces its field load experiment.The article appraises its carrying capacity by the filed loading experiment in order to further make clear the steps and gist of load experiment for steel reinforced concrete arch bridge. |
