Gravity Stone Masonry Retaining Wall Design Example

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.
Gravity stone masonry retaining wall design example. Concrete or stone masonry plain concrete gravity wall. This type of construction is not economical for walls higher than 3m. These walls are generally made of masonry and concrete. Design of retaining walls examples gravity retaining wall design.
Hollow or solid concrete masonry units used in gravity retaining walls should meet the requirements of astm c 90 ref. B semi gravity retaining walls are modification of gravity wall in which small amounts of. Cores of hollow units are typically filled to increase the weight of the wall. 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.
The masonry design standard nzs 42302004. Design and construction of stone masonry retaining walls a quick guide 1 department of engineering services 1. Introduction stone masonry retaining walls are gravity type retaining walls commonly used to retain earth or fill materials and basically retains earth pressures by virtue of its self weight. 2 and preferably have an oven dry density of 125 lb ft 2002 kg m or more.
They depend mostly on their own weight and any soil resting on the wall for stability. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. 1 should be consulted. A gravity retaining walls are constructed of plain concrete or stone masonry.
