QUESTION
Objective Question
The piping failure of a hydraulic structure can be prevented by.
Answer
( Option D)
All of these
Solution
1. Provision of sheet pile: Impermeable sheet piles are provided below the hydraulic structurs. Hence length of flow path increase and Hydraulic gradient get reduced.
2. Provision of inverted filters: Inverted filters permits movement of water but does not permit
movement of soil molecules. The pore size of filter is designed in such a way that water will
enter but soil molecules will not enter.
Hence option (d) is correct.
