design of retaining walls should address the stability of the hillside above and below a retaining wall. the stability of the hillside around a retaining wall is called global stability.
analysis software, is a fully comprehensive retaining wall analysis tool available to industry engineers. in addition, it can also contribute to certain aspects of wall stability. an example of a dead tained from a geotechnical report or soil oring log. this information is then used in the wall analysis as well as to
stability analysis of retaining wall: check factor of safety against overturning. check soil bearing pressure. check factor of safety against sliding. example s.1 cantilever retaining wall with horizontal backfill, no surcharge. example s.2 cantilever retaining wall with horizontal backfill, surcharge, and key
many of the failures associated with retaining walls can be largely attributed to lack of proper drainage. the weight of saturated soils behind the wall pushes against it, causing it to bow or even pull apart. dealing with the water causing such events is crucial to securing the retaining walls structural stability and longevity.
global stability analysis several methods of analysis such as janbu, spencer and bishop have been developed to analyze the global stability related tek: 2-4b, 15-5a, 15-8a, 15-9 keywords: factor of safety, global stability, internal compound stability ics , segmental retaining wall, soil reinforcement, tiered srw in a soil mass.
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 following conditions: groundwater table is above or within the wall height of the srw,
than steel, and construction is more rapid in comparison to conventional retaining walls. reinforced wall design is very similar to conventional retaining wall design, but with the added consideration of internal stability of the reinforced section. external stability is calculated in the conventional way; the bearing capacity must be adequate, the
retaining walls: stability analysis and construction guidelines by mohammad sadique hossain, b.s.c.e. a thesis in civil engineering submitted to the graduate faculty of texas tech university in partial fulfillment of the requirements for the degree of master of science in civil engineering appnbved accepted december, 2000
retaining wall global stability and aashto lrfd unnecessary, unreasonable guideline changes result in huge wastes of money at some wall locations the implementation of the aashto lrfd bridge design specifications includes a change in the level of conservatism for typical retaining walls with respect to overall global stability.

when introducing a tiered retaining wall system, design methodology directs us to interpret native soil conditions, the influence of slopes above and below the wall, excavation methods and the effects of the entire retaining wall system as a whole by performing global stability analysis. native soil conditions
there are two checks to consider the stability of the retaining wall. one is the check for an overturning moment and the other one is the check for sliding. the weight of the retaining wall including the gravity loads within it plays a vital role in performing the stability check. long term deflection analysis using safe program. january 28

trbs national cooperative highway research program nchrp report 611: seismic analysis and design of retaining walls, buried structures, slopes, and embankments explores analytical and design methods for the seismic design of retaining walls, buried structures, slopes, and embankments.
the global stability analysis represents a compound failure mechanism, which provides lower calculated factors of safety. the minimum safety factor is 1.3, but this factor can be increased for 1.5. further is presented the calculation of a cantilever wall and a piling wall using software slope by the geostru .

conditions of stability of retaining walls. to ensure the stability of a retaining wall, the following conditions or requirements must be met: the wall should be structurally capable of resisting the pressure applied to it. the wall should be so properly proportioned that it will not get overturned by the lateral pressure.
the design principles of gravity retaining walls are discussed below: 1. stability against overturning: the wall must be safe against overturning. overturning is caused by the horizontal component of the resultant active earth pressure, p a, in the form of an overturning moment, m o, about the toe of the wall.
