Model Stuidies on Geocell Supported Embankments Constructed Over a Soft Clay Foundation

摘要

This paper describes the results of laboratory model tests on geocell-supported earth embankments constructed over a soft clay foundation. The soft clay foundation was prepared in a large test tank to a detph of 600 mm. A single geocell layer was formed on this clay foundation with different thicknesses, and embankments were constructed above this laeyr. Four different types of geogrids were used for the formation of the geocell layer. The embankments were subjected to uniform survharge pressure on the crest until failrue. The vertical and horizontal deformations and the strains developed within the geocell layer were measured during the tests.
