某高速公路岩石单轴抗压强度结果的不确定度评定

摘要

Combining the examples in real projects,the paper has measured the uniaxial compressive strength of rocks based on the Test Methods of Rock for Highway Engineering JTG E41—2005.Evaluation and Expression of Uncertainty in Measurement JJF1059—2012 are applied to analyze and evaluate the testing results in order to learn the factors causing the deviations in the test.%依据JTG E41—2005《公路工程岩石试验规程》，结合工程项目实例，对岩石单轴抗压强度进行了试验，对试验结果采用JJF 1059—2012《测量不确定度评定与表示》进行分析与评定，了解测试中造成误差的因素，结果显示影响该项目单轴抗压强度试验的主要因素来源于样品的不均匀性和压力试验机的测量。
