ABSTRACT

The collapse of embankments, dams and slopes in the Arab world has become a phenomenon need to stand on the causes and consequences. The magnitude of the devastation due to Liquefaction phenomenon need to take the necessary precautions to reduce potential losses. Investigation of the (naturalist and imitation) of slopes and embankments stability is a hard geotechnical errand. Therefore embankments numerical study is implementing to diminish the situation of falling flat slants and rashes during shaking through appropriate FEM software. The FOS and liquefaction potential trend are obtained using finite element technique “Newmark” deformation analysis. The conformity of the analysis is verified by inquiry a layered slope of two altered soil deposits exposed to earthquake shaking. The conclusion from the study proved that the soil stratified trend has an immediate influence on the stability of the slope due to shaking and it is the simplest technique to reduce shaking effect. All combined phenomena which have delivered serious harm all over the world concentrated under quake examined under a record of 0.1 to 0.5g with particular case study to explore liquefaction zones due to the quake. Changeability of textural properties of soil layers affecting FOS and liquefaction has been examined for embankments. This study comes to put a highlight on Mosul Dam problem and give some suggestion and conclusions to its problems.
