the determination of capacity of soils, for the purpose of stability analysis of soils, for the determination of pressures on underlying strata for the calculation of settlement and the design of underground structures.
The purpose of this test is to determine the permeability (hydraulic
conductivity) of a sandy soil by the constant head test method. There are
two general types of permeability test methods that are routinely performed
in the laboratory: (1) the constant head test method, and (2) the falling head
test method. The constant head test method is used for permeable soils
(k>10-4 cm/s) and the falling head test is mainly used for less permeable soils
(k
