摘要

Compost filter socks can provide an economic "greenscape" facing for geosyn-thetic stabilized earth structures in the form of stable, vegetated retaining walls and over-steepened slopes. The socks provide a contained growth medium for new vegetation while serving as a protective slope facing that prevents soil erosion. Stability of the earth structure is achieved by geogrid sheets wrapped around the socks and embedded within a granular, compacted backfill soil. Small, portable sock modules with integrated geogrid extensions provide an alternative to the wrapped-face system and can speed up the construction process, especially for remote sites or for those sites with difficult access. Engineering experience with these types of sock-faced MSE walls has shown that the critical element in the geotechni-cal design typically is the factor of safety against sliding (FSsliding) when external stability controls the design. Thus, the practical remedy'for marginally stable MSE walls during the design process is to increase the frictional resistance along the base of the reinforced structure by increasing the length of the reinforced zone by using longer geogrids and/or by adding a base layer of compacted, high-strength granular fill (e.g., 3/4-in.-minus crushed rock). Also, these green MSE walls and RSS structures are engineered structures and must be designed and built by capable and qualified personnel. Sock-faced MSE structures provide green, sustainable options for owners and designers. With proper planning and design, such structures are eligible for LEED points in four different categories when incorporated into new construction or major renovations. L&W
