Failure of Gravity Dams – Causes and its Failure Modes
Failure of gravity dam occurs due to overturning, sliding, tension and compression. A gravity dam is designed in such a way that it resists all external forces acting on the dam like water pressure, wind pressure, wave pressure, ice pressure, ...
DESIGN PRINCIPLES OF EARTH DAMS
Design of earth dams starts with calculation of forces acting on the dam structure. The loads acting on earth dams is same as loads acting on gravity dams. Earth dams are made of non-rigid materials i.e. soil. Fig: Earth Dam ...

CRITERIA FOR DESIGN OF EARTH DAMS
The criteria for the design of earth dams are: 1. Sufficient spillway capacity and freeboard are provided so that there is no danger of overtopping of the dam 2. Seepage flow through the embankment is controlled so that the amount ...
Types of Earthfill Dams – Applications and Advantages
Earthfill dams are the most common type of dam built to any height. They are designed as a non-overflow section with separate spillway. The reason for such wide spread use of earthfill dams are: The foundation requirements are not as ...
