APPLICATION OF LASER PARTICLE SIZE AND SHAPE ANALYZER IN TESTING GRAIN SIZES OF SANDY DEPOSITS

摘要: 对辽宁海岸带75个砂质沉积物样品分别采用激光粒型仪与筛分法进行粒度测试,并对两种方法所测样品的各组分含量及粒度参数进行对比分析,探究两种分析方法之间的相关规律,从而将激光粒型仪应用于粒度分析中。结果表明,激光粒型仪所测样品的粗砂及砾石含量比筛分法所测结果偏高,而所测中、细砂含量较低,且前者所测样品的中值粒径及平均粒径均偏高,由此可得出激光粒型仪所测沉积物样品粒度偏粗。通过相关性分析得出,两种测试方法所测样品的各组分含量及粒度参数相关性均较好,其中中值粒径与平均粒径的相关系数均大于0.9。Abstract: Grain size of 75 sandy sediment samples from the Liaoning coast was measured using the laser particle size and shape analyzer and pipette-sieve method in this paper. Correlation analysis and regression equations of each definite size content and grain size parameters were analyzed for studying the law between the two analyzing methods. The results show that the content of coarse sand and gravel is higher if the laser particle size and shape analyzer is used comparing to figures measured by the pipette-sieve method. However, the pattern of median grain size and average grain size remains the same as the coarse sand, and the pattern of middle sand and fine sand content is opposite. The correlation analysis reveals that the grain sizes measured by the laser particle size and shape analyzer are coarser, but the correlation between grain content and grain size parameters of two test methods are all good, and the correlation coefficients between the median grain size and average grain size are both greater than 0.9.
