Geosynthetics reinforcement

Backfills for geosynthetic reinforced walls should be free draining,because unexpected failure of these structures can be caused by lack of control of groundwater or seepage. An appropriate geocomposite can therefore be incorporated horizontally and/or vertically to provide adequate drainage.

The concepts introduced in this entry for seismic design of MSWs have been related to margins of safety using classical notions of factor of safety. In this approach, factor of safety is simply the ratio of resistance capacity to load. In North American practice, the factors of safety against the modes of failure identified in Fig. 2 are reduced to values that are typically 75 % of static values or as low as 1.1. The exception is the factor of safety for overstressing (rupture) for geosynthetic reinforcement products which is taken as unity for seismic design. 

Such fatigue tensile tests on high-strength GTXs are necessary to evaluate the endurance of geosynthetic reinforcement materials in earth structures such as road or railroad embankments when they are exposed in the narrow zone of extreme dynamic loading.
