What is a common reason for the failure of timber retaining walls?

Adequate drainage



Compacted soil, a quality backfill aggregate, geogrids, weep holes, agricultural pipes and soil grading are all commonly used design features to stop water accumulating and causing retaining wall failure.

What are the main failure types of a retaining walls?

In addition to the three types of failures i.e. sliding, overturning and bearing failure, a retaining wall may fail in the following two modes if the soil underneath is weak.

How do you tell if a retaining wall is failing?

The three most common signs of a retaining wall in distress are (1) Leaning; 2) Cracking and 3) Bulging of the Wall or Segments. These are telltale indicators of a wall losing its fight and at risk of collapsing at any moment, including the worst possible moment: the middle of a rainstorm.

WHY DO retaining walls overturn?

This angle can be much shallower in some soils putting greater pressure on the wall. The small building is applying a surcharge load and you can how this falls into the ground as the wall fails. As the wall slips and the sand begins to fall into the gap, you can see the wall overturn.

What is a gravity retaining wall?

Gravity Retaining Walls



A retaining wall that relies solely on it’s own weight to stand up is called a gravity wall. Allan Block combines the basic engineering principles of setback, leverage and total unit mass with simple mechanics to make highly stable gravity walls.

How high can a gravity retaining wall be?

Explanation: Gravity retaining wall: It is not used for heights of more than 3.0 m. In it, the resistance to the earth’s pressure is generated by the weight of the structure.
