Retaining wall design calculator.

Check the sliding resistance for a retaining wall. 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. Retaining wall analysis bs 8002 1994 tedds calculation version 1 2 01 06 wall details retaining wall type cantilever propped at base height of retaining wall stem hstem 3500 mm. When retaining wall is designed for impact loads the stem should be checked at equally spaced points along stem length from top to the bottom as impact load spread at the greater length of the stem.

Retaining wall design temporary condition the following calculations will consider the worst case. Under normal conditions the lateral earth pressure is at rest condition. To estimate retaining wall materials using the calculator simply enter the wall length and width and the preferred block dimensions. A retaining wall refers to a structure that is designed and built up to defend the lateral pressure of soil when any alteration occurs in ground.

Poured concrete is typically the most expensive followed by wood timber and then stones and pavers. Planning a retaining wall.
