1.1. Necessity of studying Shear Strength of soils

Try these first

1. 1.

   Define shear strength in your own words.

   Hint

   Think about what happens when force is applied to the soil.

2. 2.

   What are the two main components of shear strength?

   Hint

   Remember the acronym 'CF'.

3. 3.

   What does shear strength measure?

   • A. The weight of soil
   • B. The capacity to resist sliding
   • C. The moisture content

   Hint

   Remember the definition of shear strength.

4. 4.

   Cohesion is which type of component?

   • True
   • False

   Hint

   Think about the functions of different components.

5. 5.

   Evaluate the shear strength of a soil sample given its cohesion is 30 kPa and the internal friction angle is 25 degrees. What does this imply for its use in foundations?

   Hint

   Consider utilizing parameters provided to calculate shear strength.

6. 6.

   Given a slope with 30° inclination, discuss the implications of low shear strength due to water saturation in soil stability. What preventive measures can be suggested?

   Hint

   Think about both immediate stabilization and long-term solutions.
