近年来,自然灾害引发的桥梁损害事故时有发生,尤其在地震、水灾等自然灾害频发的地区,一些早期建设的不具备防震功能的桥梁更是严重威胁着交通安全。如何提高这些桥梁的抗灾能力。以延长桥梁的使用寿命,保证交通安全成为有关部门关注的重点。本文摘自日本《建设机械》2006年11期,介绍有关桥梁防震加固技术的现状及发展,以期能使国内施工企业及桥梁维护单位有所借鉴。 In recent years, natural disasters caused bridge damage accidents have occurred, especially in the frequent earthquakes, floods and other natural disasters in the area, some of the early construction of non-shockproof bridge is a serious threat to traffic safety. How to improve the resilience of these bridges. To extend the service life of the bridge to ensure traffic safety has become the focus of the departments concerned. This article is taken from Japan’s “Construction Machinery” 2006-11, introduces the status quo and development of the bridge seismic strengthening technology, with a view to make the domestic construction enterprises and bridge maintenance units have reference.
