一、裂缝对结构正常使用的影响钢筋混凝土构件裂缝产生和发展的原因是很复杂的。在外界因素方面,有构件所处的温度和湿度条件、环境的侵蚀条件、所受荷载的大小、作用方式和时间以及构件的支承条件等等;在内部因素方面,有混凝土的施工和养护条件、配合成分、抗侵蚀性、钢筋的形状和直径、分布情况等。裂缝产生和发展对结构的使用所产生的影响也是各不相同。处于不利的温度、湿度
First, the impact of cracks on the normal use of the structure The cause of the cracking and development of reinforced concrete components is very complicated. In terms of external factors, there are temperature and humidity conditions of the components, environmental erosion conditions, magnitude of load, mode of action and time, and supporting conditions of the components, etc. In terms of internal factors, there are concrete construction and maintenance conditions. , with ingredients, erosion resistance, the shape and diameter of rebar, distribution and so on. The effects of crack generation and development on the use of structures also vary. At a disadvantage of temperature and humidity
