1-64 m 客货共线钢桁架桥荷载试验及数据分析

摘要

对某1-64 m客货共线钢桁架梁桥进行了荷载试验及数据分析研究，提出了该桥荷载的试验方法，并进行了该桥静动载试验研究，通过计算模拟分析了最不利荷载作用下该桥的受力响应，得出该试验桥梁的受力性能和正常使用状态承载能力满足设计荷载等级要求的结论。%The paper undertakes the loading test and data analysis research on 1-64 m passenger and freight line steel truss bridge,points out the loading test methods for the bridge,has the dynamic and static loading tests,analyzes the stressed response of the bridge under the most unfavor-able loading role according to the calculation simulation,and concludes the stress performance and loading capacity of the normal use status of the test can meet the design loading grading demands.
