负温高强混凝土冻结损伤纤维束模型研究

摘要

Based on the test results of frost micro pore structure density distribution of high strength concrete at minus temperat ure(HSCMT),the frost damage fiber bundle model of HSCMT was buitl.The purpose is to study frost damage factor of HSCMT in the future,to deduce lost efficiency p robability of HSCMT and prevent HSCMT from frost in cold weather.%根据负温高强混凝土冻结显微孔结构密度分布结果，建立了冻结损伤纤维束模型，为进一步研究负温高强混凝土的冻结损伤基因，推断负温高强混凝土的失效概率，及负温高强混凝土受冻害的防止打下基础。
