桥梁结构承载力加固原理分析

Analysis of bearing capacity of bridge structure reinforcement principle

桥梁加固改造技术是指对正在使用的旧桥进行检测、评价、维修、改造或加固,意在提高桥梁结构的承载力和耐久性,延长其服役年限,是当今桥梁结构研究的重要课题。对桥梁病害的诊断如同给人医病,唯有正确把握病因所在,才能做到对症下药与药到病除,因此弄清加固原理尤为重要,本文从被动和主动加固两种思想入手,讨论桥梁结构承载力加固的受力特点、原理以及有限元模拟问题。

Bridge reinforcement technology refers to the use of old bridges detection, evaluation, repair, transformation or reinforcement is intended to improve the bearing capacity and durability of bridge structures and prolonging its service life is nowadays an important subject of study of bridge structure. The diagnosis of diseases of the bridge as a healing to the person, only the right cause, to suit the remedy to the case and the problem, so find out reinforcement principle is especially important, this article obtains from the passive and active strengthening two ideas, to discuss the stress of the bearing capacity of bridge structure reinforcement characteristics, principle and finite element simulation.
