1 CONSTANT HEAD AND FALLING HEAD PERMEABILITY TEST 1 Permeability is a measure of the ease in which water can flow through a soil volume. It is one of the most important geotechnical parameters. However, it is probably the most difficult parameter to determine. In large part, it controls the strength and deformation behavior of soils. It directly affects the following: quantity of water that will flow toward an excavation design of cutoffs beneath dams on permeable foundations design of the clay layer for a landfill liner. For fine grained soil Falling head permeability test is done, whereas constant head permeability test is done for the coarse grained soil. Application Estimation of quantity of underground seepage water under various hydraulic conditions Quantification of water during pumping for underground construction Stability analysis of slopes, earth dams, and earth retaining structures Design of landfill liner Equipment Combination Permeameter assembly Stop watch Graduated cylinder (250 or 500 ml) Balance sensitive to 0.01 lb Moisture cans Drying oven Thermometer Figure 1 Sketch of the combination permeameter

4 You need to perform the following steps Allow adequate time for the flow pattern and/or specimen to stabilize. After equilibrium flow has been established, measure the time taken to have specified volume of water flowing out. Use a measuring cylinder and a stop watch. Repeat three or more times, calculating the average time. Calculations 4 The lab reports shall include the following: Sample calculations. Table showing the calculations pertinent to the permeability of the soil. Average value of permeability Calculate the void ratio by oven drying the specimen and taking the dry mass. EQUATION TO BE USED k = VL Aht (1) Where, K = Coefficient of permeability V = Collected volume of water L = Length of soil column (13.25 cm) A = Area of the soil column (31.65 cm 2 ) h = Head difference (34.3 cm) t = Time required to get V volume

5 Falling Head Permeability test 5 Procedure The following steps are already done: Compact the sample in the lower chamber section of the Permeameter, in layers approximately 1.5 cm deep, to within about 2 cm of the lower chamber rim. Use an appropriate tamping device to compact the sample to the desired density. Remove the upper section of the chamber tie rods and place the upper porous stone on the specimen, securing the upper section of the chamber with spring to the unit. Measure and record the length of the specimen. Use the clamp to attach the falling head burette to the support rod. Position the burette as high as is possible for practicality. Place the meter stick directly behind the burette, so the height of water in the burette above the chamber outflow port may be read. Saturate the specimen, following the steps outlined above. Measure the heights of the two levels from the outflow level. You need to perform the following steps After a stable flow has been established, note the drop in head (Δh) in 2 hours. (use a stop watch). Calculations The lab reports shall include the following: Sample calculations. Table showing the calculations pertinent to the permeability of the soil. Average value of permeability Calculate the void ratio by oven drying the specimen and taking the dry mass. EQUATION TO BE USED al k = ln At h h 0 1 (2) Where, K = Coefficient of permeability a = Area of the burette (1.695 cm 2 ) L = Length of soil column (13.25 cm) A = Area of the soil column (31.65 cm 2 ) h 0 = Initial height of water (56 cm) h 1 = Final height of water = h 0 - Δh t = Time required to get head drop of Δh
