Reduce the required time for measuring the permeability of clayey soils by using new manufactured cell

الملخص EN

The main objective of this research is modify new cell to find the coefficient of permeability of the clayey soil, it may be used with the variable head method.

The permeability of soils, as expressed by the coefficient K, is of considerable importance for many practical engineering problems, such as the water retaining capacity of earth dams, the capacity of pumping installations for the lowering of the ground-water level during excavations, and also the calculation of the rate of settlement of building.

The ordinary conventional permeability test takes a long time by preparing and test especially for clayey soils, this will cause some problems especially if there is a need to do a large number of this test and there are a limited number of technicians and apparatus.

From this point of view the importance of this research is clear, since the modified cell will reduce the time needed to prepare, saturated the sample and after that take the reading with time.

The modified cell made with dimension of 2 cm height and 10 cm diameter.
