The Estimation of Discharge Capacity for Vertical Drain Materials Using Composite Discharge Capacity Apparatus

Abstract

This study to estimate discharge capacity considering clogging and consolidation effects led to a development of the composite discharge capacity apparatus, followed by a series of tests with Prefabricated Drain Board (PDB) and Fiber Drain (FD). The laboratory test is done to simulate the conditions for the deformation of in-situ drain by installing the drain on the clay layer (wi=92.4%) and applying pressure on its upper part, which procedure shows a simulation where the drain is vertically installed on the surrounding ground.
