Abstract

Effect of leaching on shear strength of marine clay at Can Gio, Ho Chi Minh City is investigated in laboratory tests. Soil specimens were collected from three sites with different soil salinity. Testing includes shear strength and initial soil salinity. Leaching process is performed by modified equipment in laboratory with fresh water, then specimen is subjected to direct shear test to determine shear strength of leached and unleached soil. It is indicated that leaching affects the shear strength as reducing cohesion value (c, kPa) from 30% – 70% and internal friction angle (φ,o) from 8% - 20%.
