Abstract

Fiber drain(FD), which is made of organic fibers from jute and coir, has recently been used in several construction projects in the Southeast and East Asia region involving the soil improvement of reclamation fills overlying marine clay. FD is an environmentally friendly product that will naturally be biodegraded into soil after the completion of performance duration as a vertical drain. However, the conventional FD has limited and low-ranged discharge capacity compared to PVD. For this, in this study, the improvement of FD was attempted and new shaped FDs were evaluated by laboratory tests. A series of discharge capacity test was performed to investigate the functional applicability for several types of FDs.
