【摘要】：高原山区桥梁数量比例相对较高,但是,各种原因导致桥梁出现缺陷和病害,加之地形复杂、通信落后,无法实时、有效地监控各桥梁的健康状态.因此,急需通过先进技术进行监测和预警,提前进行预防性养护,保障人民生命财产安全.鉴于此,本文分析和梳理了影响桥梁健康的病害及其形成原因,这对桥梁监测和维护具有一定的参考意义.除此之外,本文分析并设计了基于低功耗的北斗/GPS桥梁健康监测系统,该系统利用卫星监测手段的优势,有效地解决高原山区有线通信网络覆盖不够、专业技术人员缺乏的问题,真正实现对高原山区现役桥梁的动态监测及安全评价.目前,该系统已在云南省进行实施和应用,不仅成本低、效率高,而且能够实现实时动态监测,非常适合在高原山区进行推广和应用.
[Abstract]:The proportion of bridges in highland mountainous areas is relatively high. However various reasons lead to defects and diseases of bridges in addition to the complex terrain and backward communication it is impossible to monitor the health status of the bridges in real time and effectively.Therefore, it is urgent to carry out monitoring and early warning through advanced technology, carry out preventive maintenance in advance, and ensure the safety of people's life and property.In view of this, this paper analyzes and combs the diseases affecting the health of bridges and their causes, which has some reference significance for bridge monitoring and maintenance.In addition, this paper analyzes and designs the Beidou / GPS bridge health monitoring system based on low power consumption. The system makes use of the advantages of satellite monitoring means to effectively solve the lack of coverage of wired communication network in highland mountain areas.The problem of lack of professional and technical personnel can realize dynamic monitoring and safety evaluation of active bridges in highland mountain areas.At present, the system has been implemented and applied in Yunnan Province, which not only has the advantages of low cost and high efficiency, but also can realize real-time dynamic monitoring, which is very suitable for popularization and application in highland and mountainous areas.
