桥梁橡胶支座的常见病害及其治理方法探析桥梁橡胶支座的常见病害及其治理方法探析 摘要：作为桥梁的重要组成部分，支座对桥体的安全性和耐久性影响巨大。橡胶支座因其结构简单、性能可靠、成本经济、便于施工养护等优点目前已成为最主要的支座形式，并在桥梁减震和抗大变形量等方面发挥了重要的作用。然而随着橡胶支座技术的广泛应用，其设计施工过程中的一些质量问题也逐渐显露了出来。本文分析了橡胶支座的几种常见病害形式，并通过分析其原因，提出了相应的治理对策。 关键词：桥梁工程 ， 橡胶支座，常见病害，治理 Abstract: as an important part of the bridge, the safety of the bridge bearings on the body and durability enormous influence. Because of its simple rubber bearing structure, reliable performance, cost the economy, is advantageous for the construction maintenance advantages at present has become the main bearing form, and in the bridge shock and deformation of anti-japanese has played an important role. However, with the wide application of rubber bearing technology, its design the construction process of some quality problems also gradually revealed. This paper analyzes the rubber bearings several common disease of the form, and through the analysis of the causes, and put forward the corresponding countermeasures.
