Magnitude of stress or earth pressure acting on a retaining wall depends on: height of wall, unit weight of retained soil, pore water pressure, strength of soil , amount and direction of wall movement, and. other stresses such as earthquakes and surcharges.
What you need to account for in a retaining wall is hydrostatic pressure — the force of water on and mainly in the ground that always runs downhill. When a retaining wall is in the way, water pushes against it, and the wetter the dirt becomes the more it pushes.
CHAPTER 9 EARTH PRESSURE AND HYDRAULIC . a soil–water mixture with a high . stability of the entire ground behind the retaining wall including the wall is .
If water pressure is allowed to accumulate behind a retaining wall, then the total pressure and the resulting total force along the back of the wall is increased considerably.
Engineering a Retaining Wall. . A dry, nonmortared wall allows water to seep through, relieving pressure behind the wall naturally.
where H = height of water above bottom of wall, ft Yo= unit weight of water. Unit of water is 62.4 lb/ft3 1001g/m for freshwater and 64 lb/ft3 or 1026.7 kg/m3 for saltwater. The thrust applied by water is considered to be acting at a distance of H/3 from the bottom of the retaining wall.
The pressure at any point in a fluid such as water is the same in all directions. Thus the lateral. pressure on a vertical surface retaining water is equal to γw.h where h = the height of water above. the point considered. Fig. 1 shows the lateral pressure diagram on a wall of height H retaining.

When drainage goes unaddressed hydrostatic pressure will build up behind the wall and cause damage such as bulging or cracking. There are a number of ways to ensure proper drainage of water from behind a retaining wall. First, is to make sure your landscaping contractor backfills at least a foot of space behind the wall with gravel.

When water accumulates behind a retaining wall, the lateral forces acting on the wall increase. The more water that has collected behind a retaining wall, the greater the hydrostatic pressure on the wall will be. If the overturning moment exceeds the resisting moment , the wall will fail. There are several ways to prevent water from building up behind a retaining wall.
