随着基础建设的迅速发展,桥梁建设中大体积混凝土应用越来越多,混凝土在现代桥梁工程建设中已经占据了非常重要的地位,因为该建筑材料价廉物美,施工方便,承载力大,可装饰强。但是,在使用混凝土的同时,由于对混凝土的性能了解不深,在工程完工一段时间后,混凝土结构物出现了裂缝或其他不良反应,给人们的心中造成担忧和后怕的感觉。本文从分析大体积混凝土温度裂缝产生的原因入手,试图找出影响裂缝大小的因素,总结出有价值的控制措施,供工程技术人员参考。
With the rapid development of infrastructures, the mass concrete used in bridge construction is more and more used. Concrete has occupied a very important position in the construction of modern bridges. Because the building materials are cheap and cheap, the construction is convenient and the carrying capacity is high, Can be decorated strong. However, while using concrete, due to the poor understanding of the performance of concrete, some time after the completion of the project, the concrete structure cracks or other adverse reactions to the hearts of people cause fear and scared feeling. Based on the analysis of the causes of temperature cracks in mass concrete, this paper attempts to find out the factors that affect the size of cracks and summarize the valuable control measures for the reference of engineering technicians.
