摘要
新疆北部某水利工程是我国在严寒地区修建的第一座百米级全断面碾压混凝土重力坝,冷、热、风、干气候特征突出,本文从大体积混凝土温度标准与温控措施两方面进行研究及实践,使混凝土结构体产生裂缝的几率将大大降低,尤其可以大幅度减少深层贯穿性裂缝产生的几率,提高混凝土结构体的安全度。
Some a hydro project of North Xinjiang, the first hectometer grade full section roller compacted concrete gravity dam, is built in severe cold area in China, which has the prominent climatic characteristics of cold, hot, wind and arid. Through research and practice of temperature standards and temperature control measures for the mass concrete, the occurrence frequency of the crack in concrete structural body is greatly decreased,es p ecially for the deep penetrating cracks. Therefore, the security of the concrete structural body would be improved.
