Mostly the hydraulic structures founded on ____________ soils fails because of undermining and uplift pressure?
Correct answer: A. Permeable
- A. Permeable
- B. Rocky
- C. Impermeable
- D. Stable
Explanation
Permeable foundation soils allow seepage beneath a hydraulic structure, producing uplift pressure and piping or undermining at the downstream exit. Impermeable or sound rocky foundations are much less susceptible to these seepage failures.
