Download Solution PDFClayey Soils in Central Impervious Cores of Zoned Earthen Dams:
- Pure clayey soils are generally avoided in the central impervious cores of zoned earthen dams.
- One of the main reasons for this is that clays are susceptible to cracking under certain conditions, particularly due to drying or when subjected to differential settlement.
- When cracks develop, they can compromise the impervious nature of the core, leading to potential leakage or failure of the dam.
- Therefore, clays' susceptibility to cracking makes them a less preferred choice for the central impervious core.
