Factor of safety against sliding in retaining wall

calculate the factor of safety with respect to sliding, overturning and bearing capacity. These three components are important elements in retaining wall design. Structural design of a retaining wall is beyond the scope of this course. Content Section 2 Categories of Lateral Earth Pressure. It will be considerable pressure on the retaining wall. For example, when we take soil pressure for friction angle 30 degrees, it is 0.33 x 20 h = 6.67h. The water pressure will be 10h. Here, soil density considered as 20 kN/m3. Sol pressure without water = 6.67 h. With water = 0.33 (20 -10) h + 10 h = 13.3 h.

The factor of safety against sliding is defined as forces preventing sliding along the bottom divided by the forces that will cause sliding along the bottom surface. Factor of safety should not be less than 1.5 for sliding condition. Factor of safety against overturning Consider force acting on the gravity retaining wall with the lever arm as .... Chapter 14 - Retaining Walls July 2021 14-7 14.1 Introduction Retaining walls are used to provide lateral resistancefor a mass of earth or other material to accommodate a transportation facility. The walls are used in a variety of applications se including right-of-way restrictions, protection of existing structures that must remain in place,.

Is Per is 456 the factor of safety against overturning for a retaining wall is? The factor of safety against sliding of structures which resist lateral forces (such as retaining walls) shall be not less than 1.5 when dead load, live load and earth pressures are considered together with wind load or seismic forces... Spacing of bars. d) Design of Shear Key. Considering a factor of safety against sliding 1.5. Horizontal force reqd. to resist sliding . Restoring force available. Force to be resisted by the key.

The safety factor against lateral sliding shall be taken as the available soil resistance at the base of the retaining wall foundation divided by the net lateral force applied to the retaining wall. Exception: Where earthquake loads are included, the minimum safety factor for retaining wall sliding and overturning shall be 1.1.

The following elements were part of the safety factor standardization process: • Traditional factors of safety specified in previous Corps guidance documents were used as a basis for establishing new factors of safety, which are re-formatted to be consistent with other Corps guidance that has probabilistic based requirements.

The factor of safety against overturning is defined as the resisting moment divided by the overturning moment, and the minimum value should be 1.50. As an example, the picture below shows the ASDIP RETAIN overturning calculations. Note that the load combinations are based on service loads, since the wall stability is being checked.
Known Parameters : Height of earth Retained, h = m. Unit weight of soil = kN/m2. Unit weight of concrete = kN/m2. angle of internal friction of soil, φ = °. Slope of backfill, β = °. soil-wall interface friction, δ = °. Surcharge pressure on backfill, w s = kN/m2.
concept of safety factor; i.e., a safety factor of unity should correspond to limiting equilibrium, and hence to finite stresses. It is apparent that the factor 11a does not provide a satisfactory measure of the safety against overturning, although this factor is com monly used for just this purpose. The difficulty lies in the fact that
