The Auger borings are not common A. In soils that require lateral support B. In cohesive soils C. In soft soils D. None of the above

In soils that require lateral support
In cohesive soils
In soft soils
None of the above

The correct answer is: A. In soils that require lateral support.

Auger borings are a type of soil boring that uses a rotating auger to remove soil. They are typically used to investigate the subsurface conditions of a site before construction. Auger borings are not common in soils that require lateral support because the auger can easily collapse in these soils.

Cohesive soils are soils that have a high clay content. They are relatively strong and do not require lateral support. Soft soils are soils that have a low clay content. They are relatively weak and require lateral support.

Here is a brief explanation of each option:

  • Option A: In soils that require lateral support. Auger borings are not common in soils that require lateral support because the auger can easily collapse in these soils.
  • Option B: In cohesive soils. Cohesive soils are soils that have a high clay content. They are relatively strong and do not require lateral support.
  • Option C: In soft soils. Soft soils are soils that have a low clay content. They are relatively weak and require lateral support.
  • Option D: None of the above. This option is not correct because auger borings are not common in soils that require lateral support.
