Foundation Failure Causes
Foundation failure is a critical issue in construction and can occur due to several factors. These include:
-
Unequal settlement of subsoil: When subsoil settles unevenly due to differences in load distribution or soil properties, it can cause cracks and instability in the foundation.
-
Shrinkage of soil bed: Certain soils, like clay, shrink significantly when they lose moisture. This can lead to voids beneath the foundation, compromising its structural integrity.
-
Lateral escape of soil: If soil laterally moves or escapes due to external forces such as water pressure or excavation nearby, the foundation may lose its support and fail.
Analyzing the Given Options
-
Option 1: Unequal settlement of subsoil: (Correct)
-
Uneven settlement causes structural stress and leads to cracks or tilting.
-
-
Option 2: Shrinkage of soil bed: (Correct)
-
Shrinkage reduces soil volume, creating voids and weakening the foundation's support.
-
-
Option 3: Lateral escape of soil: (Correct)
-
When soil moves laterally, the foundation loses necessary support and stability.
-
-
Option 4: All of the above: (Correct Answer)
-
Since all the given causes contribute to foundation failure, this is the correct option.
