Water Pressure. It is the pressure of water that acts perpendicular on the upstream face of the dam. For this, there are two cases: A. Upstream face of the dam is vertical and there is no water on the downstream side of the dam Fig.1.
Uplift pressure or Seepage Loads. When the water is stored on the upstream side of a dam there exists a head of water equal to the height up to which the water is stored.
Earthquake Forces. Dynamic loads created due to earthquakes must be considered in the design of all major dams located in ‘high-risk’ seismic regions, and for dams situated in close proximity to potentially active geological fault complexes.
Self-Weight of Dam. The weight of dam and its foundation is a major resisting force. It can be computed using the following equation: Where: : unit weight of dam material.
Silt Pressure. The weight of dam and its foundation is a major resisting force. It act at h/3 from the base and can be computed using equation 12: Where: : coefficient of active earth pressure of silt which equal to : angle of internal friction of soil, cohesion neglected.
