Some results of unconfined compressive strength testing of soil by trixial compression equipment
Abstract
The unconfined compressivestrength test is to determine the compressive resistance strength of the soil sample, characterizing the bearing capacity of the soil ground. The author uses trixial compression device to perform the unconfined compressive strength test with the advantage that Loadcell records the automatic reading instead of the mechanical clock reading of the crank device. Experiments have recorded the results of 3 soil groups as follows: For sandy soil with gravels, plastic state gravel (viscosity B from 0,29 to 0,37; number of SPT from 7 to 12 hammers), the compressive resistance strength changes from 62,08 to 105,55 kN/m2. For sandy clay with gravels, soft plastic state (viscosity B from 0,49 to 0,61; the number of SPT from 2 to 7 hammers), the compressive resistance intensity varies from 48,95 to 99,77 kN/m2. With sandy clay with gravels, stiff state (viscosity B from 0,21 to 0,42; number of SPT from 7 to 19 hammers), the compressive resistance intensity varies from 52,78 to 162,69 kN/m2.
