6) guarantee rate
保证率
1.
With the calculation of two practical examples,the results show that the guarantee rate of concrete core strength central value from cast-in-situ concrete pile based on Quality Inspection and Evaluation Standards for Highway Engineering(JTJ071-98) i.
2个混凝土强度检测案例的计算结果表明,利用《公路工程质量检验评定标准》(JTJ071-98)进行灌注桩芯样混凝土强度代表值确定,得到的代表值保证率在95%左右波动,具有不确定性;利用《超声回弹综合法检测混凝土强度技术规程》(CECS 02:88)进行单一构件混凝土强度推定,推定值的保证率小于95%,对结构的可靠性鉴定而言是偏于不安全的,应引起试验检测人员的充分重视。

补充资料：保证率
水利工程在多年期间能使规定的任务要求得到满足的程度，以百分数计。其概念与水文数理统计上的频率同。例如某工程供水保证率为75％，即表示该工程就长期平均而言，100年中有75年可保证正常供水,而不是每100 年中一定能（或只能）有75年保证正常供水。水利规划中对各项任务要求一般都要选定某一设计保证率作为规划标准，并据以决定工程的规模。表达的方法因任务而异。防洪、除涝等属于对水灾的控制，其保证率多以通过措施可使防护对象不受洪、涝危害的某一重现期的洪水或暴雨表示。灌溉、发电、航运、供水等均属对水资源的利用，其保证率则是以通过措施能满足有关用水要求不受破坏的机遇表示。设计保证率的选定是国家在一定时期中技术政策和经济政策的具体体现。保证率越高，付出的代价越大，承受的风险越小；保证率越低，付出的代价越小,但所需承受的风险势必越大。通常,各项任务的设计保证率都要在规划中根据其重要性、特点，结合国家或地区的经济状况和有关工程的自然条件，通过技术经济论证最终选定。
