摘要

A full scale instrumented trial embankment test was conducted to evaluate theeffects of the Rammed Aggregate Pier (RAP) System on the very soft claysunderlying railway a proposed embankment test site in the island of Luzon, thePhilippines.A 5.0m high trial embankment was on a Section of a 10 kilometer stretch ofrailway on relatively very soft marshy ground to simulate embankment loads and theimpact of train loads on railway embankments of the NORTHRAIL Railway.The study was initiated to prove that consolidation time in very soft clayscould be accelerated by the lateral prestressing and prestraining effects of therammed aggregates piers on the subgrade and the enhanced drainage effect of theRAP body.This paper discusses the test embankment construction, instrumentation andmonitoring and the geotechnical exploration to gather soil parameters. Thetheoretical settlement calculations and field observations served as the bases for thefindings reported.The results of the settlement monitoring program revealed that significanttime savings could be realized during railway embankment construction if the RAPSystem is utilized, because time to full consolidation was accelerated to four (4)weeks instead of the calculated 6 to 8 months using other conventional groundimprovement systems.
