The action of geotextiles in providing combined drainage and reinforcement to cohesive soil

This thesis describes a study into the action of geotextiles in providing combined drainage and reinforcement to cohesive soil and the identification of the interaction of different geotextiles with a cohesive soil. The study involved both experimental and analytical investigations. Fine grained coh...
