Infiltration tests on reinforced clay wall and test embankment

Infiltration tests are performed both on geosynthetic-reinforced clay walls and a test embankment to investigate the permeability of compacted clay and the stability of reinforced clay walls under heavy rainfall condition. Various soil pre-processing and compaction methods are introduced on low plasticity Alluvial clays for the construction of the walls and test embankment. Outward displacements of wall facings between 5 and 10mm are measured during 50 days of water infiltration on the entire top surface of the reinforced walls. Some consistent test results are also obtained in the infiltration test performed on the top of test embankment using single-ring tube method.
