【摘要】 水工混凝土材料抗裂性(抗裂指数)与水工混凝土结构抗裂性(抗裂安全系数)是两个不同的概念,不能混淆。通过对水工混凝土材料抗裂性影响因素的分析,提出了考虑因素全面、物理意义明确的混凝土材料抗裂指数计算公式,并对几个水工混凝土结构抗裂安全系数公式进行了评价,最后提出提高水工混凝土结构抗裂性的技术措施。更多还原

【Abstract】 The crack-resistance of hydraulic concrete material(crack-resistance index) and hydraulic concrete structure(safety factor of crack-resistance) are two different concepts,which can not be obscured.This paper introduces the effect factors on crack-resistance of hydraulic concrete material.The author advances the crack-resistance index calculation formula of hydraulic concrete material,which all influential factors are considered and physical meaning of formula is explicit.Appraising the safety factor of crack-resistance calculation formula of hydraulic concrete structure,the author puts forward improving technical measures on crack-resistance of hydraulic concrete structure.更多还原
