RESULTS: The optimized values of parameters for naphthalene were a) permeability coefficient
for the stratum corneum 6.8 x [10.sup.-5] cm/hr, b) permeability coefficient
for the viable epidermis 3.0 x [10.sup.-3] cm/hr, c) fat:blood partition coefficient 25.6, and d) other tissue:blood partition coefficient 5.2.
The design requirements can be satisfied only when the transverse permeability coefficient
of the drainage layer is larger than the transverse permeability coefficient
of the extreme rainfall intensity.
Rainfall infiltration rate depends on rainfall intensity as well as the water permeability coefficient
and the hydraulic gradient of topsoil.
Figure 8 shows the influence of [k.sub.h]/[k.sub.hw] on consolidation behaviour of CCSG pile composite foundation under three different patterns of horizontal permeability coefficient
. It can be seen that when the horizontal permeability coefficient
within soil is smaller than that within the sand-gravel shell, the consolidation rate is accelerated limited with the decrease of [k.sub.h]/[k.sub.hw].
where [lambda] = (xcos [alpha]/2) [square root of [mu]/K[H.sub.m]t,] K is the permeability coefficient
(m/d), [H.sub.m] is the aquifer thickness (m), [mu] is the specific yield, t is the time of the water level decrease (d), and [h.sub.0,0] is the reservoir water level before it began to decline.
The adsorption coefficient and permeability coefficient
can be used to evaluate the migration of water within the material.
where G and [lambda] are the Lame constants; [[epsilon].sub.v] is the volumetric strain; p is the pore water pressure; [x.sub.j], [u.sub.j], and [f.sub.xj] are the coordinate, displacement, and volume forces in j direction, respectively; K is the permeability coefficient
; and S is the storage coefficient.
where K - f([[sigma].sub.e], P) is the empirical formula of the coupled stress and fluid flow, [[sigma].sub.e] is the effective normal stress, and K is the permeability coefficient
3,  which was used to calculate the permeability coefficient
of the biphasic system with lamellar morphology:
Figure 22 plots the link between the permeability coefficient
and the collapse and fracture pressure.
The coefficient of permeability is then determined based on Darcy's law A minimum permeability coefficient
of [10.sup.-2] cm/s ([approximately equal to]100m/day) is commonly recommended for the pervious pavement structure [18,19].
