Gabion Retaining Wall Design Manual

Gabion retaining wall systems are monolithic gravity mass structures that are ideally suited for erosion control applications and follow standard design methods for gravity and mse retaining walls.

Gabion retaining wall design manual.

The use of link gabions and mattresses helps to ensure that drainage is maintained but like all retaining structures a careful assessment of drainage. That may be associated with traditional retaining structures or scour structures. 5 professional engineers are unlikely to approve this design of wall. 4 some local building regulations define the height as the distance from the base to the top of the retained soil.

Design begins with the selection of trail dimensions for a typical vertical cross section through the wall. For advice or assistance with the design of an economical gabion wall please email our engineer gabion1 co uk. This tutorial offers 5 steps on how to build a gabion wall especially handy tips for starting your first gabion project. The use of horizontal layers of wire mesh as a horizontal tie back or soil reinforcement is discussed separately.

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. 3 retaining wall size needs to be increased to resist added load. When constructing gabion retaining walls in strongly acidic soils ph over 5 5 the soil and the corrosive groundwater must be separated from the gabion structure by using geotextile fabrics and a properly designed drainage system. 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.

Gabions are a great way to construct retaining walls garden beds rock wall features seating and numerous other landscape features. The design code applicable to gabions is bs 8002 the code of conduct for earth retaining. Gabion walls may be stepped on either the front or the back soil side face as illustrated in figure 1. The following information is provided as a guide to assist contractors and do it your selfers in the proper construction of gabion retaining.

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. Four main steps must. The design of gravity retaining walls e g. The problem of inadequate drainage behind retaining walls is often a source of major wall failure.

The design of both types is based on the same principles. 9 3 2 2 1 p in respect of unplanned excavation. The design does not consider that the gabion mesh provides improvement to stability.
