为了充分掌握桥梁结构的实际工作状况,对其实际承载能力进行评定,判断桥梁的实际工作状况是否符合设计要求或处于正常受力状态。通过进行科学有效的静载试验能够达到良好效果。静载试验实施阶段,通过对桥梁结构的应力、应变及挠度测试,能够充分掌握荷载作用下,桥梁状态究竟如何,这样才能实现桥梁安全判定,营运安全方面才能得到充分保障。本文从静载试验实际案例着手,探讨试验原理以及相关内容,阐述相应测试及分析方法,力求实现试验结果更加科学准确,对桥梁结构实际工作状态作出正确评定,并提出相应的处理建议。
In order to fully grasp the actual working conditions of the bridge structure, evaluate its actual carrying capacity, and judge whether the actual working conditions of the bridge meet the design requirements or are in a normal stress state. Through the scientific and effective static load test can achieve good results. Static load test implementation phase, through the bridge structure stress, strain and deflection test, can fully grasp the role of the load, the bridge status, so as to achieve the bridge safety assessment, operational safety can be fully protected. This paper starts from the actual case of static load test, discusses the principle of the test and its related content, elaborates the corresponding test and analysis methods, tries hard to achieve more scientific and accurate test results, correctly evaluates the actual working status of the bridge structure, and puts forward corresponding handling suggestions.
