| Abstract: | A case study of an earth dam under construction in the Siwalik sedimentary rocks in North India is presented. The dam site is located in a seismically active zone. The shear zones incorporated in the rocks during folding control the stability of the dam foundations. Because the shear zones crop out in the river bed at different locations along the dam axis, the dam foundation is comprised of discrete blocks of varying resistance. The mechanism of stability is greatly influenced by the disposition of shear zones and the relevant analysis is three dimensional. |
