Protecting geomembranes from animal damage

June 1, 2017  |  Case Studies

Resisting animal and insect attacks on geomembranes is an interesting problem. Geomembrane installers and manufacturers have had numerous geomembranes damaged by bears, deer, coyotes, birds, beavers, and ground squirrels (Figures 1 and 2). In most cases, the damage is incidental to something else th…
Part 2: New design models for MSE walls and slopes

June 1, 2017  |  Case Studies

Introduction The design of many geotechnical structures is based on limit-state conditions. For example, in designing gravity walls, the load exerted by the retained soil on the wall is based on an assumed active state of stresses. That is, the wall moves sufficiently outward, enabling the retained …
