Document Content and Description Below

CM 3503 Quizzes 4-7 A normally consolidated soil is one that has a present effective pressure (stress) less than that which the soil has been subjected to in the past. T or F - ANS-False As the com... pactive effort increases, the optimum moisture content will increase and the maximum density will increase. T or F - ANS-False; optimum moisture content decreases Compaction is defined as the ____________________ of soil by removal of ____________________ by means of ____________________ energy - ANS-densification; air & water; mechanical energy Given the wet unit weight equal to 118 pcf and a moisture content of 10 percent, calculate the dry unit weight to one place after the decimal point. - ANS-107.3 Hydraulic conductivity (k) depends upon which of the following soil parameters a. grain size distribution b. void ratio c. fluid viscosity (temperature) d. degree of saturation e. saturated unit weight f. all of the above g. a, b, c, and d but not e - ANS-g. grain size distribution, void ratio, fluid viscosity, degree of saturation Immediate settlement is the predominate settlement for a gravel or sandy soil. T or F - ANS-True In-situ methods for determining shear strength of soils include the following: Cone penetration test, vane shear test, pocket penetrometer, pressure meter, and borehole shear test. T or F - ANS-True Settlement can be caused by deformation of soil particles. T or F - ANS-True Settlement cannot be caused by expulsion of water from voids. T or F - ANS-False Soil Compaction is accomplished by which mechanisms: [Show More]
