JJF1311-2011《固结仪校准规范》已于2011年12月14日起正式实施。该规范实施一段时间后,笔者发现了一些问题,在此提出,与广大计量专家交流。一、杠杆式固结仪输出力值校准点的选取杠杆式固结仪的工作原理是用砝码通过杠杆对土壤试样施加轴向压力,来测定土壤试样的轴向变形与压力的关系和变形与时间的关系,每级压力施加的准确与否直接影响着土壤试样的测定结果。JJF1311-2011之
JJF1311-2011 “consolidation instrument calibration standard” has been December 14, 2011 came into effect. After the implementation of the norm for a period of time, the author found some problems, proposed here, and the majority of measurement experts exchange. First, the lever-type consolidation instrument output value calibration point selection Lever-type consolidation instrument works by using the weight of the lever through the axial load on the soil sample to determine the relationship between the soil sample axial deformation and pressure And the relationship between deformation and time, the accuracy of each level of pressure applied directly affects the determination of soil samples.
