CHAPTER 2INDEX AND CLASSIFICATION PROPERTIES OF SOILS2-1.From memory, draw a phase diagram (like Fig. 2.2, but don’t look first!). The “phases” havea Volume side and Mass side. Label all the parts.SOLUTION:Refer to Figure 2.2.2-2.From memory, write out the definitions for water content, void ratio, dry density, wet or moistdensity, and saturated density.SOLUTION:Refer to Section 2.2.2-3.Assuming a value ofρs= 2.7 Mg/m3, take the range of saturated density in Table 2.1 for thesix soil types and calculate/estimate the range in void ratios that one might expect for these soils.SOLUTION:Create a spreadsheet using input values from Table 2.1 and Eq. 2.18.ρ' - minρ' - maxemaxemin(Mg/m3)(Mg/m3)0.91.40.890.210.41.13.250.551.11.40.550.210.91.20.890.420.00.1∞16.000.30.84.671.13(Given)(see Eq. 2.18)Preview Mode
