在水利工程建设过程中,普遍存在大体积混凝土的施工过程,最常见的是混凝土坝。由于多方面因素,在其施工过程中常会出现各种裂缝,这在水利工程中不仅会降低建筑物的抗渗能力,影响建筑物自身的稳定、安全性能,而且会加剧混凝土的碳化过程,是内部钢筋锈蚀,从而降低建筑物的耐久性,影响建筑物的承载能力,从而给下游的生命财产安全带来隐患,因此,我们必须充分、认真的分析裂缝产生的原因,不断提高施工工艺,尽可能的将裂缝宽度控制在合理范围内。
In the process of water conservancy construction, the construction process of mass concrete is prevalent, the most common is concrete dam. Due to many factors, cracks often occur in the construction process, which will not only reduce the impermeability of buildings, affect the stability and safety of buildings themselves, but also aggravate the carbonization process of concrete. Internal steel corrosion, thereby reducing the durability of the building, affecting the carrying capacity of the building, which brings hidden dangers to the life and property downstream, therefore, we must fully and carefully analyze the causes of cracks and continuously improve the construction process, It is possible to keep the crack width within a reasonable range.
