NUMERICAL ANALYSIS OF THE DYNAMIC BEHAVIOR OF THE EARTH DAM – CASE STUDY OF THE OURKISS DAM, ALGERIA.

Toufik karech, Hassiba baghzim

Abstract


The analysis of failure due to the effect of propagation of normal and reverse faults with different angles of inclination and by slip through the Ourkiss dam is studied numerically.The study is done mainly at the end of the construction and at the highest water level. The non-linear finite difference method is used considering four angles of inclination of the fault, active at the centre of the dam base.The results of the study show that the shear stress values increase with the increase of the vertical displacement of the imposed base in both the empty and filled dam conditions, for both normal and inverted faults.


Keywords


Earth dam, normal fault, reverse fault, shear stress, Failure path.
