Global/Slope Stability Analysis
February 1st, 2024
Q: My question stems from the fact that (in my area) there still seems to be confusion over when a global/slope stability analysis is required and who is responsible. A contractor might ask for some budget pricing for retaining wall design. Generally, this is in regards to a segmental retaining wall design. The challenging part […]
Improving the performance of geosynthetic reinforced SRW by design
February 1st, 2024
FIGURE 1 Geogrid reinforced segmental wall, about 3.6 m (12 feet) design height, typically utilized in the private sector. Note the unreinforced broken backslope which has moderate rise. In many cases such backslope is rather steep, 1(v):2(h), and long thus rendering significant rise. The wall in this photo is located in a highly seismic area […]

Part 2: New design models for MSE walls and slopes
June 1st, 2017
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 soil to mobilize its shear strength along a […]
