Abstract
A pilot test using natural fiber drains was conducted to prove their effective discharge capacity in the field. The pilot test site was divided into 5 different areas, with various combinations of vertical and horizontal drains installed for evaluation. Conventional PDB and FDB, as well as the newly developed SDB, were used as vertical drains, while sand and fiber mats were used as horizontal drains. Based on the monitoring data obtained at the test site, the surface settlements which occurred at PDB, FDB and SDB installation fields were almost identical as well as laboratory model test results. The excess pore pressure measured in SDB was greater than that in PDB and FDB, while the dissipation rate of excess pore pressure in SDB was slower than that in PDB and FDB. The generation and dissipation rates of excess pore pressure measured in the ground from the installation of PDB, FDB and SDB were almost identical to the same extent as the surface settlements measured at the pilot test field. Based on the existing data, natural fiber drains represent a promising alternative material for the improvement of soft clay.
