Observations of pore water pressure

settlement and lateral displacement were carried out and consolidation coefficient and consolidation degree were calculated based on the observed data in a foundation treatment with prefabricated strip drains at a seaside ground. The results of static penetration test

vane shear test

standard penetration test and plate load test after consolidation indicated reinforcements of foundation and increases of stabilization in 50 days. It is shown that the reinforcing foundation with prefabricated strip drains is an effective measure at seaside ground.
