2.2. Causes of Failure

Try these first

1. 1.

   Define overturning in the context of dam failure.

   Hint

   Think about the balance of forces acting on a dam.

2. 2.

   What causes sliding in dam structures?

   Hint

   Consider the relationship between force and friction.

3. 3.

   What is a primary cause of dam overturning?

   • Excessive water pressure
   • Strong foundation
   • Material strength

   Hint

   Think about what external factors are acting on a dam.

4. 4.

   True or False: Sliding occurs when frictional forces overcome horizontal forces.

   • True
   • False

   Hint

   Recall how forces interact in a dam structure.

5. 5.

   A high reservoir level is causing the dam's overturning risk. Outline strategies to mitigate this risk, considering construction material and structural design.

   Hint

   Consider both engineering solutions and material choices.

6. 6.

   Assuming a dam is experiencing significant sliding due to lateral forces from seismic activity, what design changes could enhance its stability?

   Hint

   Think about how to strengthen the foundation.
