Gravity Retaining Wall Design Calculations

8 3 2 1 gravity retaining walls gravity wall dimensions may be taken as shown in fig 8 3 a.

Gravity retaining wall design calculations.

One is the check for an overturning moment and the other one is the check for sliding. The civilweb gravity retaining wall design spreadsheet is a easy to use design spreadsheet which can be used to design concrete retaining walls in accordance with bs en 1997 and bs en 1992. Walls formed from interlocking concrete blocks are designed as gravity walls defined in bs 8002 2015 as follows. There are a variety of materials you can use to build a retaining wall including patio stones wood and poured concrete.

The factor of safety against sliding may be expressed by the equation. A review of basic soil. The wedge is defined as the soil which extends beyond the failure. I m now doing the calculations so much faster and easier than doing it manually and most importantly the technical customer service team are great and they respond instantly and professionally to any.

Retaining wall cost varies by material. The top width of the stem should be not less. The civilweb gravity retaining wall design spreadsheet completes all the calculations instantly. Gravity wall is an intuitive program for gravity retaining walls design.

A retaining wall that relies solely on it s own weight to stand up is called a gravity wall allan block combines the basic engineering principles of setback leverage and total unit mass with simple mechanics to make highly stable gravity walls. Refer to figure a 4 for the mass or weight calculations. 1 should be consulted. Although wall heights up to 8 ft 2 44 m for conventional gravity walls and 14 ft 4 28 m for soil reinforced walls are presented properly engineered walls can exceed these heights.

Try it for free without analysis restrictions. Retaining walls instantly enhance any landscape design. For a detailed discussion of design and analysis parameters the design manual for segmental retaining walls ref. Poured concrete is typically the most expensive followed by wood timber and then stones and pavers.

The weight of the retaining wall including the gravity loads within it plays a vital role in performing the stability check. Setback sliding wedge. Figure a 4 retaining wall weight components. Basic calculations needed to design a retaining wall.

Gravity retaining walls are earth retaining structures that depend primarily on their own self weight and that of any enclosed material to support the retained ground and any structures or loads placed upon it. Other topics include sheet pile walls tilt up retaining walls soldier pile walls gabion walls counterfort walls pilaster walls and walls with pile or pier foundations. Every retaining wall supports a wedge of soil. Restrained basement walls gravity walls and segmental retaining walls both gravity and with geogrids.

The base and other dimensions should be such that the resultant falls within the middle one third of the base.
