大准铁路增二线黄河特大桥静载试验分析

Analysis of the Yellow River bridge under static load of the dazhun railway additional second line project

桥梁荷载试验是一项复杂而细致的工作,技术含量高,涉及面广。桥梁荷载试验的目的是对新建桥梁竣工验收和已建桥梁运营时进行承载力的评定,检测桥梁整体受力性能是否满足设计和标准规范要求,是评定桥梁运营荷载等级最直接和最有效的办法。本文对大准铁路增二线工程黄河特大桥的静载实验方法进行了介绍,通过理论计算与试验结果对比分析,对黄河特大桥桥梁结构的的性能指标进行评价,为桥梁的维修养护提供技术资料。

Bridge load test is a complex and painstaking work, high technology content, involving a wide range of. The purpose is to the newly built bridge completion acceptance and bearing capacity assessment for the bridge have been built. The stress performance whether or not to meet the design requirements and standards.Bridge load test is the most direct and efficient way to evaluation of bridge operation load level. This paper introduces the static load test method of the Yellow River Bridge of the dazhun railway addition-al second line project,through theoretical calculations and experimental results comparative and analysis, evalu-ated the performance indicators of the bridge structure,and provided technical information for the repair and maintenance of the bridge.
