桥梁伸缩缝是桥梁构造中的重要组成部分,伸缩缝问题现在仍处于探索研究中,在气温变化、混凝土收缩、活载作用、桥梁墩台的沉降及徐变等因素影响下,桥跨结构会产生变形,从而使梁端产生位移。它对公路车道的平整度影响较大,而且是桥梁的整体结构安全的决定因素之一。在此主要介绍了公路桥梁伸缩缝的施工设计与施工质量控制等内容。针对桥梁伸缩缝的质量控制方法谈几点体会和建议。
Bridge expansion joint is an important part of the bridge structure. The expansion joint problem is still under exploration and research. Under the influence of temperature changes, concrete shrinkage, live load, settlement and creep of bridges and abutments, Produce deformation, so that the beam end displacement. It has a greater impact on the flatness of road lanes and is one of the determinants of the overall structural safety of the bridge. Here mainly introduces the highway bridge expansion joint construction design and construction quality control and so on. Talk about the bridge expansion joint quality control methods to talk about some experience and suggestions.
