RESEARCH AND INNOVATION; SEISMIC PERFORMANCE OF VARIOUS GEOCELL EARTH-RETENTION SYSTEMS by Dov Leshchinsky
This article provides an overview of the research where the use of geocells as an earth-retention structure was explored; and specifically the seismic performance of gravity walls and reinforced walls utilizing PRS Neoweb was evaluated.
The author states that while the performance of both types of walls under seismic loading (at the level equivalent to the 1995 Kobe Earthquake in Japan) was excellent, these are based on HDPE geocells that are suitable for short term use.
Dr. Leshchinsky concludes with guidelines for the development of PRS' new generation NeoloyTM polymer technology with long-term stiffness, enabling its effective use in reinforcement for earth retention, load support in pavements and railroads and more....
