36.7. Factors Influencing Site Response Spectrum

Try these first

1. 1.

   What effect do soft soils have on seismic waves?

   Hint

   Think about how rigidity affects wave movement.

2. 2.

   What is the relationship between depth to bedrock and wave amplification?

   Hint

   Consider how waves interact with soil depths.

3. 3.

   What type of soil amplifies low-frequency waves?

   • Soft Soil
   • Hard Soil
   • Rock

   Hint

   Think about the flexibility of the soils.

4. 4.

   True or False: Greater depth to bedrock generally leads to less wave amplification.

   • True
   • False

   Hint

   Consider how waves behave as they move through different layers.

5. 5.

   Given a site with 20m depth to a very soft soil layer, assess the expected seismic response compared to a shallow layer of hard rock.

   Hint

   Relate the concepts of depth and soil type to wave behavior.

6. 6.

   Evaluate the impact of varying topographies on seismic wave propagation in two different regions, one mountainous and another flat.

   Hint

   Consider how shapes influence wave dynamics.
