混凝土在现代工程建设中占有重要地位。在水利工程建设中尤为重要.随着混凝土材料和施工技术的飞速发展,人们相应的对混凝土温度应力及温度控制和施工质量控制提出了更高要求。混凝土的裂缝较为普遍,在水利工程中裂缝几乎无所不在。究其原因,施工者对混凝土温度应力的变化注意不够是其中之一。 Concrete occupies an important position in the construction of modern engineering. It is particularly important in the construction of hydraulic engineering.With the rapid development of concrete materials and construction technology, people put forward higher requirements on temperature stress, temperature control and construction quality control of concrete. Concrete cracks are more common, cracks in water conservancy projects almost everywhere. The reason, the construction of concrete temperature stress change is not enough attention is one of them.
