基于损伤识别的桥梁预防性养护研究

Research on Preventive Maintenance of Bridges Based on Damage Identification

桥梁工程受到地质条件、气候环境等外界因素影响,容易产生各种损伤,使得桥梁的耐久性与承载能力降低,影响其使用寿命,因此,开展桥梁的损伤识别及预防性养护工作就显得尤为重要。本文结合工程实例建立ANSYS有限元分析模型,根据实测数据,展开损伤识别研究,提出相应的预防性养护措施,为桥梁养护和管理提供了参考和借鉴。

Bridge project as an important part of infrastructure construction in China,due to the influence of geological conditions,climate,environment,and prone to all kinds of damage,reduces the durability of structure and the bearing capacity,damage to the actual service life,therefore,bridge damage identification and preventive maintenance is particularly important.Based on this,this paper establishes ANSYS finite element analysis model based on the engineering example,identifies the damage of the project according to the measured data of the project,and puts forward the corresponding preventive maintenance measures,which provides a reference for the bridge maintenance and management.
