Strata Systems Inc. has announced an upgrade to its advanced interactive computer software program designed to assist engineers with the design and analysis of geogrid-reinforced steep slopes.
Earthen slopes up to 70 degrees from horizontal can be safely designed in accordance with methodologies accepted by the Federal Highway Administration and U.S. Army Corps of Engineers for a multitude of project applications. The program, named StrataSlope, is now available for use by experienced geotechnical and civil engineers familiar with the technology of mechanically stabilized earthen structures.
The updated software provides current product material properties, thereby offering designers a knowledge stream that ensures their material selection will be accurate, effective and long-lasting.
"Developing highly advanced soil reinforcement products is a serious undertaking," said Lance Carter, P.E., Strata's technical director. "It requires a thorough analysis of countless variables that pertain to manufacturing materials, as well as site-specific conditions. Our customers want an effective tool in evaluating the stability of their reinforced soil structures. That's where StrataSlope software fits in."
The software considers tie-back and compound stability using log-spiral failure surfaces, direct sliding via conventional two-part wedge mechanism and deep-seated stability analysis utilizing Bishop's Method of Slices. StrataSlope is ideal for reinforced soil slope applications and is effective for basic global stability evaluation of retaining walls.
Optimized for the design of reinforced slopes, the software accommodates complex geometries with up to three different soil zones (reinforced, retained and foundation), along with inclined toe and top slopes. Additional software elements included are three uniform surcharge areas, options to include pore water pressure and seismic stability factors. StrataSlope is fully compatible with U.S. or international design standards such as BS 8006.
