公路与桥梁混凝土的施工温度与裂缝防治研究

Research on Construction Temperature and Crack Preventionof Highway and Bridge Concrete

公路桥梁是重要的交通基础设施,对于促进社会经济发展具有十分重要的作用,因此必须高度重视公路桥梁工程的施工质量。混凝土是公路桥梁工程的主要施工材料之一,但是混凝土由于自身的物化特点比较容易受到温度因素的影响而出现裂缝,这不仅直接关系到公路桥梁工程整体结构的完整性和稳定性,还会给公路桥梁的通行安全带来风险。因此,施工单位必须采取有效的裂缝防治措施,充分确保公路桥梁质量和安全。

Highway bridges are important transportation infrastructures and play a very important role in promoting socio-economic development. Therefore, great attention must be paid to the construction quality of highway bridges. Concrete is one of the main construction materials for highway bridge engineering. However, concrete is more suscep tible to temperature and cracks due to its physical and chemical characteristics, which not only directly affects the in tegrity and stability of the overall structure of highway bridge engineering, but also gives The safety of road bridges poses risks. Therefore, the construction unit must take effective crack prevention measures to ensure the quality and safety of highway bridges.
