Stability of slopes of an earth dam is tested under, which of the following condition?
The stability of slopes of an earth dam is tested under the following condition:
a) Stability of downstream slope during steady seepage and Stability of upstream slope during a sudden drawdown
Let's understand why this option is the correct answer:
Stability of downstream slope during steady seepage:
When water seeps through the downstream slope of an earth dam, it creates a hydraulic gradient. This hydraulic gradient exerts pressure on the slope, which can potentially cause instability. Therefore, it is essential to test the stability of the downstream slope during steady seepage conditions to ensure that it can withstand the hydraulic forces and remain stable.
Stability of upstream slope during a sudden drawdown:
During a sudden drawdown, the water level on the upstream side of the dam decreases rapidly. This sudden change in water level can induce significant stresses on the slope. The decrease in water pressure can cause the soil particles to rearrange, potentially leading to slope failure. Therefore, it is crucial to test the stability of the upstream slope under sudden drawdown conditions to ensure that it can resist the induced stresses and remain stable.
None of the mentioned:
This option is incorrect because the stability of slopes of an earth dam needs to be tested under specific conditions, as mentioned above.
All of the mentioned:
This option is incorrect because the stability of slopes of an earth dam does not need to be tested under all possible conditions. Only the stability of the downstream slope during steady seepage and the stability of the upstream slope during a sudden drawdown are the relevant conditions for testing the stability.
In conclusion, the correct answer is option 'A,' which states that the stability of slopes of an earth dam is tested under the stability of the downstream slope during steady seepage and the stability of the upstream slope during a sudden drawdown.
