Estimating live loads in MSE wall and slope design

June 1st, 2018

In formulating a factor-of-safety value for a mechanically stabilized earth (MSE) wall or slope project, a design engineer calculates a ratio of resisting forces to driving forces. This contrast is further recognized when using load and resistance factor design (LRFD), which is in our not-too-distant future. The resisting forces are the soil’s inherent properties (e.g., […]

Monitoring the performance of Louisiana’s first GRS–IBS bridge

June 1st, 2018

Over the decades, soil mass reinforced by layers of geosynthetics has been used widely and successfully in a variety of earth structures, such as mechanically stabilized earth (MSE) retaining walls, embankments, slopes and shallow foundations. Due to the proven benefits of geosynthetic reinforced soil (GRS), including cost-effectiveness, simple and fast construction, and tolerance of differential […]
