Gravity Walls

This wall depends on its self-weight for its stability. It is designed so in which the overturning effect of the lateral earth pressure does not induce tensile stresses inside the section. This is used for walls of low height and is not economical for large heights. Gravity walls have been established of stone, bricks, mass concrete and precast concrete blocks.

The cross section of the wall is trapezoidal along with a base width among 0.3 and 0.5 H, where H is the height of the wall. The top width varies from 0.2 to 0.3 m. For concrete, a top width of 0.3 m is recommended for proper placement of concrete.
