摘要
从构件抽检数量、混凝土强度推定公式及构件检测结果真实性判别等方面,分析了《回弹法检测混凝土抗压强度技术规程》、《建筑结构检测技术标准》和《民用建筑可靠性鉴定标准》中关于混凝土构件强度推定的规定和计算方法,认为《建筑结构检测技术标准》对于混凝土强度推定值是否合格有一个较明确的结论,并通过算例分析表明,《建筑结构检测技术标准》在检测数量上更为灵活,但其检测结果会比其它规范计算得出的值要高。由于规范对于强度推定真实性的判别方法不一样,得出结果也会不一样。
The method of calculating on the strength derived value is introduced from three aspects： the number of sampling inspection, the formula of the strength derived value and the facticity of the strength derived value, It shows that Technical standard for inspection of building structure （TSFIOBS） will give a definitude conclusion on the strength derived value, which is eligible or not. It suggests that TSFIOB S will be flexible in the number of sampling inspection, while the result of sampling inspection will be larger than others, calculated from the other standards. Further more, it will come to a different result when the method of the estimating on the facticity of the strength derived value is different.
