an information series from the national authority on concrete masonry technology ncma tek replaces tek 1 segmental retaining wall global stability introduction the general mass movement of a segmental retaining wall srw structure and the adjacent soil is called global stability failure. global stability analysis is an important component of srw design, particularly under the …
equilibrium slope stability calculations show the slope is stable with and without the protection/facing. the stability of the facing must be assesse d as failure may have an adverse impact on downslope areas. retaining walls critical to a building foundation: a retaining wall is considered critical to the
we know there is an audience out there wanting this kind of stuff, and the gaming conventions we're familiar with are so limited; the craft of video game design is still so young so i don't think

retaining walls types, design, stability. retaining walls may be defined as a wall built to resist the pressure of liquid, earth filling, sand, or other granular material filled behind it after it is built. it is commonly required in the construction of hill roads, masonry dams, abutments and wings walls of bridges and so on. depending upon the site conditions, type of material to be

global stability is the stability of the hillside above and below a retaining wall. by it's very existence, a retaining wall changes the shape of a hillside. these changes should be addressed by the engineer and contractor to determine if the hillside is stable. take a look at these sketches, photos and video:
aashto requires all retaining walls have adequate factors of safety for global stabilty for both static and seismic. retaing walls that support abutments have higher factors of safety. the engineer of record in my opinion should be responsible for ensuring global stability.
