摘　　要：误差分析是土力学实验的重要环节,以土力学土粒比重实验为例,论述了利用实验原理分析误差产生的来源。通过误差预判、过程控制、问题导引和误差设计等手段,减少了实验过程中的错误操作,加强了学生对实验原理与误差原因的理解,达到了培养学生思维能力和科学素养的目的。Error analysis is an important link of the soil mechanics experiment.By taking the experiment of Soil Specific Gravity of Soil Mechanics as an example,the analysis on the source of error generation by using the experimental principle is expounded upon.By means of the error prejudging,process control,problem guidance,error design,etc.,the error operation of the experimental process is reduced,the students’ understanding of the experimental principle and cause of the error has been strengthened,and the purpose of cultivating the students’ thinking ability and scientific literacy is achieved.

关 键 词：实验误差 土力学 误差分析 误差设计
