Gabion Retaining Wall Design Calculations

When building gabions on softer soils both the depth of the toe and the size of the base needs to be increased to spread the load over a wider area.

Gabion retaining wall design calculations.

The design does not consider that the gabion mesh provides improvement to stability. Units of gabion wall are considered as one cohesive mass for design purposes. Design examples appendix a. Wood retaining walls 14.

3 0 design guide for lane gabion walls 3 1 gravity wall design lane gabion walls are generally analyzed as gravity retaining walls that is walls which use their own weight to resist the lateral earth pressures. Segmental retaining walls 17. The design of gabion retaining walls is based on the mass of the contained stone or rock being able to resist the disturbing forces due to soil and external loadings. Swimming pool walls 18.

Gabion walls may be stepped on either the front or the back soil side face as illustrated in figure 1. The retaining wall toe prevents the gabion wall sliding forwards the depth of the toe needs to increase as the wall gets bigger. The use of horizontal layers of wire mesh as a horizontal tie back or soil reinforcement is discussed separately. Pilaster masonry walls 19.

The design code applicable to gabions is bs 8002 the code of conduct for earth retaining. Design begins with the selection of trail dimensions for a typical vertical cross section through the wall. Sheet pile walls 21. The main forces acting on the wall are lateral earth pressure at the back face and vertical forces which is the weight of the wall as shown in figure 4 the latter force is employed to resist the.

The design of both types is based on the same principles. How retaining walls fail. Calculations this post is also available in. 9 3 2 2 1 p in respect of unplanned excavation.

Construction topics and caveats 24. Dutch french the design and calculations are based on the coulomb method and conform the britisch standard bs8002 which state that the security factor against overturning fo has to be 2 and the security factor against sliding fs has to be 1 5. When building gabions on softer soils both the depth of the toe and the size of the base needs to be increased to spread the load over a wider area. Four main steps must.

The design of gravity retaining walls e g. Gabion wall is designed in the same way as gravity retaining wall. Restrained non yielding walls 20. Soldier pile walls 22.

Gabion retaining walls can be designed and configured with a stepped front face or a smooth front face. With traditional procedures for retaining wall design.
