Question

Consider the following statements about Bligh's Creep theory for seepage flow:
1. The loss of head is proportional to the length of creep.
2. For all types of soil, Bligh's coefficient is constant..
3. The hydraulic gradient must be kept under a safe limit in order to ensure safety against piping.
4. Generally, the thickness of floor is increased by 33%, so as to allow a suitable factor of safety.
Which of the above statements are CORRECT?

• A. 1, 2 and 3
• B. 2, 3 and 4
• C. 1, 2 and 4
• D. 1, 3 and 4

Answer 1

The correct option is D 1, 3 and 4

Bligh's coefficient is different for different type of soils.
