Relation of Permeabilities Between Materials 2 and 3A of the El Cajon Dam
Material 2 of the El Cajon dam,constitutes a uniform support of the face of concrete and protects against filtration effects;as well as material 3A protects to material 2.By specification,k2 must be equal or smaller than 10-3 cm/s and k3A greater than 10-1 cm/s,with a relation of k3A/k2= 100. Tests of permeability in the curtain indicated fulfilment of material 2,not that material 3A where smaller values to the specified ones were obtained.Detailed analyses more indicate that material 3A himself fulfils the function of filter by resistance to the internal erosion and like material of retention of material 2. The condition of greater permeability is not fulfilled,nevertheless,by the first condition is most important much,thus is guaranteed hydrodynamics stability of materials 2 and 3A.
