Your question is not clear, I am not sure what you are asking for. Anyway, soil strength is a measure of the capacity of soil to resist applied pressure without deformation. Soils which are unable to bear the applied pressure result in collapse of engineering structures, for example, earthen dams under pressure of impounded water, sliding of pavement or other structures on unstable sloppy lands. Strength of cohesive soils declines under wet conditions and increases under dry and compacted conditions. There are different laboratory test to estimate soil strength but the simplest is the 'direct unconfined compression test'.

Hello Dear Mr Tarafdar

Thank you for your reply,Assume two granular soil samples prepared and cured identically but with diffrent cementing agent to be tested under unconfined compression test, one  is a rigid and hardened body and the other is a little more resilient , So after being tested under aforementioned conditions the hardened sample does produce a big peak strength but axial strain is less about for example 2 percent and the other one  exhibits more deformation and reaches failure at bigger strain assume 4 percent, but the maximum strength is less than the other sample, in usual practice which one is more of acceptance, higher strength but bearing small strains or lesser strength but enduring large strains

Again Thanks a lot.

I think one should prefer the resilient  one, may be lesser strength but enduring large strains.
