钢筋混凝土桥梁检测技术
摘要
本文概括地介绍了公路桥梁检测的一些基本内容对钢筋混凝土桥梁检测技术与流程做了简要概述。针对筋混凝土桥梁的现有技术状况,对桥进行有关项目的检测,根据检测结果对其病害及病害成因进行了分析,可为桥梁的病害治理及文修加固决策提供科学可靠的依据.主要介绍了本文源自优文论文网外观检查、材料特性检查、结构受力性能检查等检测内容的目标、方法及实现过程,桥梁在一个国家的交通运输和经济发展中占有重要位置。桥梁的检测是保证桥梁安全运营的重要手段。本文对我国目前桥梁结构检测情况进行阐述和分析,并列举了桥梁结构检测的方法。

ABSTRACT
This article broadly introduced highway bridge examination some basic contents examined the technology and the flow to reinforced concretebridge Liang have made the brief outline. In view of the muscleconcrete bridge existing technical condition, carries on the relatedproject to the bridge the examination, according to examined theresult has carried on the analysis to its plant disease 毕业论文http://www.Lwfree.cn/ 论文网http://www.Lwfree.com/the and so on structurestress servicing check goal, the method and the realization process,the bridge holds the important position in a national transportationand the economical development. The bridge examination is guaranteesthe bridge security operation the important method. This article atpresent the bridge structure examination situation carries on theelaboration and the analysis to our country, and has enumerated thebridge structure examination method.
