Question: 5 . 3 7 . Geosynthetic - encased granular columns are installed in normally consolidated soft soil with an undrained shear strength of 1 0

5.37. Geosynthetic-encased granular columns are installed in normally consolidated soft soil with an undrained shear strength of 10kPa. The diameter of the columns is 0.5m. The total unit weight of the soil is 16kNm3 and its effective friction angle is 20. The friction angle of the granular column is 36. The geosynthetic encasement has an allowable tensile strength at 5% strain is 20kNm. Calculate the ultimate bearing capacity of a single geosynthetic-encased column considering possible bulging failure.
