Gravity Retaining Wall Design Calculations

There are a variety of materials you can use to build a retaining wall including patio stones wood and poured concrete.

Gravity retaining wall design calculations.

The civilweb gravity retaining wall design spreadsheet completes all the calculations instantly. The weight of the retaining wall including the gravity loads within it plays a vital role in performing the stability check. Restrained basement walls gravity walls and segmental retaining walls both gravity and with geogrids. Figure a 4 retaining wall weight components.

1 should be consulted. The top width of the stem should be not less. 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. 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.

Planning a retaining wall. Setback sliding wedge. Retaining wall cost varies by material. The wedge is defined as the soil which extends beyond the failure.

Poured concrete is typically the most expensive followed by wood timber and then stones and pavers. 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. Basic calculations needed to design a retaining wall. The factor of safety against sliding may be expressed by the equation.

8 3 2 1 gravity retaining walls gravity wall dimensions may be taken as shown in fig 8 3 a. Walls formed from interlocking concrete blocks are designed as gravity walls defined in bs 8002 2015 as follows. The base and other dimensions should be such that the resultant falls within the middle one third of the base. 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.

One is the check for an overturning moment and the other one is the check for sliding. Gravity walls generally are trapezoidal in shape but also may be built with broken backs. Refer to figure a 4 for the mass or weight calculations. 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.

Every retaining wall supports a wedge of soil. Gravity wall is an intuitive program for gravity retaining walls design. For a detailed discussion of design and analysis parameters the design manual for segmental retaining walls ref. Retaining walls instantly enhance any landscape design.

ʃf r sum of the horizontal resisiting forces ʃfsl sum of the horizontal driving forces figure 8 2 indicates that the shear strength of the soil immediately below the base slab may be expressed as.
