December 4 Webinar - Geosynthetic-Stabilized Roads Webinar

GEOSYNTHETIC-STABILIZED ROADS

Geotextiles, geogrids, and geocells have been used widely in roadway stabilization works throughout the world. In this webinar, Dr. Jie Han will deliver an introduction to geosynthetics in roadway engineering. His presentation will focus on the mechanisms involved in geosynthetic stabilization of unpaved and paved roads. Dr. Han is one of the leading practitioners in this area of geosynthetic design and research, and his work has contributed significantly to field understanding on how we can improve soil mechanical properties with geosynthetics and how these design decisions may involve two different functions/mechanisms—reinforcement and stabilization—which depend on geosynthetic/soil properties and loading conditions. The webinar will illustrate the differences and relationships between reinforcement and stabilization by geosynthetics in roads and discuss the selection of proper geosynthetics for specific applications based on controlling mechanisms.

Dr. Jie Han is the Glenn L. Parker Professor of Geotechnical Engineering in the Civil, Environmental, and Architectural Engineering Department at the University of Kansas. He has nearly 30 years of teaching, research, and practical experience in geotechnical and pavement engineering focused on geosynthetics and ground improvement. Dr. Han has authored more than 300 peer-reviewed journal and conference papers as well as the text Principles and Practice of Ground Improvement.

ABOUT THE NOVEMBER 1 WEBINAR

Conventional design of geosynthetic-reinforced soil structures is divided into two categories, walls and slopes, based on the batter of the facing system. Internal stability, characterized as sufficient reinforcement anchoring and strength, is performed using earth pressure-based design criteria for reinforced walls, while reinforced slopes are founded on limit equilibrium (LE) slope stability analyses. LE analyses are also used to assess the global or compound stability of both types of structures, accounting for the geometry of the reinforced, retained, and foundation soils.

A Different Approach towards Limit State Design of Geosynthetic-Reinforced Soil Structures

The application of LE-based methods typically results in determination of a slip surface corresponding to the lowest attained Safety Factor (SF), known as the Factor of Safety (Fs); however, it yields little information about reinforcement or connection loading. In this presentation, Dr. Ben Leshchinsky will show how the use of the analyzed spatial distribution of SF (known as a Safety Map) can be modified to attain a prescribed constant Fs at any location in the reinforced soil mass. This modified framework directly enables the determination of a Tension Map that illustrates the required distribution of reinforcement tension to attain a prescribed state of equilibrium. To illustrate the utility of the Limit State framework, a series of instructive examples will be presented. The results of this design approach demonstrate the effects of facing elements, closely-spaced reinforcements, and secondary reinforcement layers. Comparison will also be provided to conventional design approaches.

Ben Leshchinsky, Ph.D., P.E. is an associate professor in geotechnical engineering at Oregon State University. His primary research interests focus on slope stability, reinforced soil, and applications of geomechanics towards assessment of natural hazards.
