Answer 2

GRAVITY DAM

A gravity dam is subjected to hydrodynamic pressure caused by the increase in water pressure momentarily caused by the horizontal earthquake acting towards the reservoir.

KEY TAKEAWAYS FOR GRAVITY DAM:

* A gravity dam is a structure made of concrete or stone masonry that is meant to keep back water by relying only on the weight of the material and its resistance to the foundation to counteract the horizontal pressure of water pressing against it. Each portion of a gravity dam is designed to be stable and independent of the other dam sections.

* Gravity dams are often built on stiff, high-bearing-strength rock foundations (little weathered to fresh), however they have been erected on soil foundations in exceptional situations. The foundation's bearing strength restricts the resultant force's permissible position, affecting overall stability.
