Mechanical Properties of Compacted Solidified Granular Mud

Granular solidification technique for soft mud have been studied using some original neutral conditioners in addition to solidification materials. The cone index has adopted to evaluate the improvement effect of the soils. In order to apply the treated muds as filling materials, mechanical properties of the compacted soils should be studied. The permeability test and the series of the unconsolidated undrained triaxial compression test have conducted for the soils. The target cone index were set between 400 kN/m2 and 800 kN/m2. The coefficients of permeability depended on the amount of added stabilizer and were between 1×10-4 m/s and 1×10-8 m/s. Under unconsolidated undrained condition, the friction angles were under 10 degree regardless of the sorts of original mud or stabilizing material, and the cohesion were under 60 kN/m2 depended on the cone index. The modules of deformation of the treated muds increased with the maximum deviator stress increased.
