我们采用SHARP PC-1500袖珍计算机计算、整理土的粒度分析资料,取代了原来用计算尺、点绘曲线图等工序。对提高计算精度和工作效率,均获得了较好效果。 土的粒度分析试验的比重计法主要根据司笃克定律来测定土粒在水中下沉的速度,以确定土的粒径大小和占土重的百分数。 由于计算公式较复杂,资料整理的繁琐,通常计算,整理一组数据需要15分钟左右,现采用计算机计算一组数据只需两三分钟即可。
We use the SHARP PC-1500 pocket computer to calculate and sort the soil particle size analysis data, replacing the original use of the ruler, dot plotting and other processes. For the improvement of calculation accuracy and work efficiency, all have obtained good results. Soil Particle Size Analysis The pycnometry of the test is based primarily on Span’s law to determine the rate at which soil particles sink in water to determine the size of the soil and the percentage of soil weight. Due to the complexity of the calculation formulas and the tediousness of data collection, it usually takes about 15 minutes to calculate and sort a set of data. Now it takes only two or three minutes to use a computer to calculate a set of data.
