kslee1000 is correct. In order to realize passive resistance you must fully mobilize the soil's shear strength, i.e. fail the soil mass in front of the toe. The amount of strain needed to realize fully passive resistance is much greater than that needed to realize active.
Rockjoint,
The opposite of well graded is well sorted, indicating that the majority of the grains are of simular size, i.e. poorly-graded.
Poorly sort means there isa range of grain sizes. The same as well graded.
I know that I am showing my bias, but what about Karl Terzaghi. He practically invented moderned soil mechanics and geottchnical engineering. made a science where, before, much was guess work.
I posted this thread in the general Civil Forum, but I believe this forum is more appropriate.

Jefferys,
How are you diferentiating N(avg) and N(bar)?
Also, we have those who try to average the properties in the upper 100ft even if there is not 100 ft of soil. and thrying to say the average values are great enogh to get a C.
