1. The following results were obtained from particle size distribution analysis of three soils A,B and C. Required: (1) Plot the particle size distribution curves (semi-log). Determine the following quantities of each soil: the effective particle size d10, the mean particle side d50, the coefficients of uniformity and curvature (if possible). (2) According to the particle size distribution, when the engineering properties are concerned, which soil is the most sensitive to water and which soil is mostly affected by density? Give you logic. (3) Classify the soils according to the USCS. 1. The following results were obtained from particle size distribution analysis of three soils A,B and C.
