For tge same soil, draw both drying and wetting SWCCs. Discuss the differences between the wetting and drying SWCCs.

Describe about the dry soil mixing procedure.

Describe about the Deep Soil Mixing procedure.

Ex Two identical soil samples (A) and (B) of a fully saturated N.C.C. were tested. Sample (A) was subjected to an unconfined compression test and failed when the deviator stress (OT-13) was (200) kN /n². Sample (B) was tested under UU conditions with a cell pressure of (300) kN/m². The pore water pressure at failure. was (200) kN/m². a) What was the pore water pressure at failure in sample (A). b) If C=o, Find (2) for this clay. (Itint. Start with soil B, and that (OJ) un= (FJ) afined). unconfined
