摘要
混凝土拱坝在浇筑过程中,由于水泥水化热的大量产生,致使混凝土内部会或多或少地产生一些微裂纹,这些微裂纹在外部荷载的作用下,开始发展、汇集、贯通,最终形成宏观裂缝,危及坝体安全。所以对拱坝浇筑过程中产生的温度裂缝研究是一项十分重要的工作。
In the casting process of the concrete arch dams,the cement hydration heat generated a lot,so the concrete internal will more or less to produce some slightly crack.Under the effects of external loads,the cracks will eventually develop into big cracks and endanger the safety of the dam.So the construction process of arch dam temperature cracks generating is a very important work.
