The civilweb stone masonry retaining wall design spreadsheet comes complete with analysis tools which can be found nowhere else on the market. The coefficient of friction between the footing and foundation soil k 1 is 0 25 and the allowable soil bearing pressure is 2 000 psf 95 8. Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall. A gravity retaining walls are constructed of plain concrete or stone masonry.

The main purpose is to provide standard designs of stone masonry retaining wall that can be easily followed by engineers in the field.

These walls are generally made of masonry and concrete.

This type of construction is not economical for walls higher than 3m. Design and construction of stone masonry retaining walls a quick guide 2 department of engineering services 2. B semi gravity retaining walls are modification of gravity wall in which small amounts of. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.

Retaining wall retains earth when level difference exists between two surfaces. Concrete or stone masonry plain concrete gravity wall. The masonry design standard nzs 42302004. Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.

Flexural and shear stresses in gravity retaining walls will almost always be of minor importance. Hence this attempt to condense simplify and compile information from many sources including my own experience into this book. They depend mostly on their own weight and any soil resting on the wall for stability. Scope this guideline provides the fundamentals of design of stone masonry retaining walls.
