Unformatted text preview: The University of Iowa Department of Civil & Environmental Engineering 53:030 Soil Mechanics Fall Semester, 2003 Lab Experiment No. 5: Constant Head Permeability Test Equipment: constant head permeameters, glass beakers or graduated cylinders, timers, and a thermometer. A. Objective In this laboratory experiment, the constant head test will be employed to measure the hydraulic conductivities of three different soil types: A sandy soil (FI-6); A crushed limestone aggregate (CLA-2); and A gravel (GRA-1). You measured the grain-size distributions for soil FI-6 in Lab 2, and the GSD for CLA-2 AND GRA-1 are provided below in Figure 1. In addition, you should observe the relative impermeability of soil FI-10 whose GSD you measured in Lab 2. (For this soil, quantitative measurements are not required, just an observation that the flow rates through this soil are much smaller than those through the sandy and gravelly soils. Please consider why this is so.) B. Experimental Procedure Since the experimental apparatus for these tests has already been set up the procedure for this experiment...
