Unformatted text preview: Soil Mechanics CEG 3011 Homework 6 Spring 2010 Problem 1 : Refer to the figure below and determine elevation, pressure and total heads for points A (on top of soil 1), B (bottom of soil 2), and C (at the interface between soils 1 and 2). h 1 = 300 mm, h 2 = 5 mm, h 3 = 180 mm, H 1 = 200 mm and H 2 = 150 mm Problem 2 A layers soil is shown in the following figure. Estimate the equivalent hydraulic conductivity for flow in the horizontal direction. Estimate the equivalent hydraulic conductivity for flow in the vertical direction. Calculate the ratio of Kv(eq)/Kh(eq). Problem 3 A cylindrical sample of soil is confined in a rigid wall permeameter and measures 10 cm in diameter and 20 cm in length. The axis of the cylindrical sample lies in a horizontal plane. The hydraulic head (pressure head) at the left of the sample is controlled by a reservoir; the water surface in the reservoir is exactly 100 cm above the horizontal axis of the cylindrical soil sample and remains at 100 cm through a system that adds...
