Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.

6. 7. Calculate the induced vertical stress at point A at a depth of 5 feet. The surface stress in the shaded areas is 3000 lb/ft2. Hint: The contributions of the shaded areas must be calculated separately and then added together. The contribution from the lower area will require the use of imaginary rectangles. (Answer: 1892 lb/ft2, yours may differ slightly) Four 40' diameter fuel tanks are constructed in a square pattern. The tanks apply a maximum surface pressure of 5000 lb/ft2. The spacing of the tanks is 50 feet center- center. What is the induced vertical stress beneath the center of the area at depths of 20 feet and 50 feet?
