Classification of. Retaining walls. • Gravity wall-Masonry or Plain concrete. • Cantilever retaining wall-RCC. (Inverted T and L). • Counterfort retaining wall- RCC. Types of reinforced concrete retaining walls are cantilever retaining walls and counterfort retaining walls. Functions and parts of these retaining walls. In this type of retaining wall, counterforts (cantilevers) are provided on the earth side between wall and footing to support the wall, which essentially spans as a.

The overturning moment is stabilized by the weight of wall and the weight of the soil above the heel slab the weight of soil over the toe is neglected. Monte Carlo method Search for additional papers on this topic. The brackets in this case are known as buttresses and by ckunterfort of their location they are subjected to compressive forces.
From This Paper Figures, tables, and topics from this paper. The lateral pressure imposed by this load does not vary with the height and is counterfor. This is shown in pressure diagram in Fig. You are currently using guest access Log in. In addition, it should be ensured that no dall is developed at the base i. Due to buoyancy the weight of submerged soil will be less and its repose will also be much less.
The foundations of the retaining wall should be placed at such a depth where soil of required bearing capacity is available. In this type of wall the base slab as well as the stem of the wall span horizontally as continuous slabs between vertical brackets known as counterforts as shown in Fig.
This buttressed wall is identical to a counterfort retaining wall with the main difference that the vertical brackets are provided in front of the wall on face opposite to the face retaining back fill as shown in Fig. Hence total lateral earth pressure at the base of wall is given by. To avoid failure of the retaining wall it is necessary that the following requirements are satisfied. Based on the method of achieving stability, retaining walls are classified into the following types: The size of the wall is so kept that there is no tensile stress developed at any section of the wall under any condition of loading.
Four Types of Concrete Retaining Walls – The Concrete Network
The sliding tendency is resisted by the frictional resistance between the base of the tetaining and the soil underneath. How well do we know what we are doing? References Publications referenced by this paper. The pressure mainly depends upon the type of backfill material and the height of wall.
Four Common Types of Rigid, Monolithic Concrete Retaining Walls
It may also be defined counetrfort a wall provided to maintain ground at two different levels. Wall with backfill levelled and subjected to uniform surcharge. The maximum and minimum pressure are given by. Wall retaining partly submerged backfill: When the height of the retaining wall to be provided exceeds 6 to 7m, counterfort retaining wall prove to be economical.
Wall retaining submerged backfill: Risk assessment in geotechnical engineering. The lateral pressure due to the backfill and surcharge if any tends to overturn the retaining wall about its toe.
The wall consists of three components, i the stem, ii the toe, and iii the heel. The base width b of the retaining wall vary between 0. If the water table is such that the retained soil remain fully submerged, in such a case the saturated soil results in increasing the weight of the backfill, decreases the angle of repose of the soil which ultimately amounts to increase in pressure on the wall.

Towards reliability-based design for geotechnical engineering Kok Kwang Phoon Design of Lintel with Sunshade. The pressure distribution is triangular.
In this case wall has only two components i. Probability, reliability and statistical methods in engineering de-sign. Before proceeding with the structural design it is necessary to ensure that the preliminary dimensions assumed for the various components of the wall will render it safe against above referred types of failures.
