Abstract

Overview

ISO 18325:2015 defines an index test method for determining the water discharge capacity of prefabricated vertical drains (PVDs). Intended for conformance and acceptance testing, the standard quantifies how much water a PVD will convey under specified hydraulic gradients and simulated soil stresses, including both straight and buckled drain geometries. Key aims are reproducible measurement of index discharge capacity (expressed in ml/s) and guidance for test apparatus, specimen preparation, and reporting.

Key topics and technical requirements

Test principle: Measures PVD discharge while simulating intrusion of the geotextile into the core, core deformation and buckling, confining pressure and hydraulic gradient effects.
Apparatus: Pressure cell with slots, water reservoir and head-control system, buckling device, flexible synthetic-rubber membrane (thickness
