混凝土作为桥梁工程必不可少的一个重要组成部分,在我国目前的桥梁工程中得以广泛应用。但是由于在施工和使用过程中混凝土经常出现的裂缝却一直困扰着桥梁工程技术人员,甚至于因为裂缝而影响工程质量最终导致桥梁垮塌的事故屡见不鲜。本文作者通过对桥梁混凝土的设计、施工、监理、运营管理等多方面进行研究,对桥梁混凝土因上述各环节的因素可能产生裂缝的原因进行分析、总结,以方便设计、施工找出控制裂缝的可行办法,达到防范于未然的作用。 As an indispensable part of bridge engineering, concrete is widely used in the current bridge engineering in our country. However, frequent cracks in concrete during construction and use have plagued bridge engineers and even accidents that affect the quality of the project due to cracks eventually lead to the collapse of bridges. Through the research on the design, construction, supervision and operation management of bridge concrete, the author analyzes and summarizes the possible causes of cracks in the bridge concrete due to the factors mentioned above, in order to facilitate the design and construction to find the control cracks Feasible way to achieve a preventive effect.
