![]() By theoretical analysis appeared that when the water reservoir was connected to the flood level, a problem may occur in the downstream face of the dam lead to seepage failure. Thus, one cross-section is selected for different elevations (minimum, normal and maximum or flood design elevations) to compute the seepage of water, pore water pressure and phreatic line. To achieve the research goals, a study was carried out on Hemrin dam, which located in the Diyala River 100 km northeast of Baghdad, Iraq. The SEEP / W software (program) is a sub-program of the Geo-Studio software, which is used by porous soil media to compensate for the problems of seepage. The primary focus for this reason is the discretization of domain into finite elements through the placement of imaginary nodal points and the discretization of governing equations into an equation system An equation for each nodal point or part, and unknown variables are solved. Pore water pressure during the earthquake.įinite Element Approach is employed in this research work to solve the governing differential equations related to seepage via its foundation's dam structure. Was analyzed to earthquakes at the normal and the maximum water level, and by using a quake that may haveīeen exposed to Iraq in 2017 and used the time of 100 seconds and using an acceleration of 0.02g, 0.03g,Ġ.05g measured by units of ground acceleration to identify the behavior of displacements, effective stress and The impact of different water levels on the stability of the body dam. The stability of the dam was studied under the influence of earthquakes of different intensity, and a review of This paper includes an analytical study of the effect of thisĮarthquake on Al-wand earth dam, using the quake/w program, which is a sub-program of geo-studio, also Simulating Al-Wand earth dam through numerical modeling and study the influence of water reservoir level,Įarthquake peak acceleration, and duration. This research project mainly aims to study the behavior of Al-Wand earth dam under seismic load in different conditions by Wand earth dam (the subject of the study) is located, was exposed to several earthquakes. Reason for this research, in general, in 2017, the whole of Iraq, and in particular the region, where the Al. The change in the seismic zone that recently Iraq affected is the The effect of earthquakes on earth structures. Therefore, a geotechnical engineer needs to know The seismic can be threatened the stability of the flexible body of the earth dam and can cause completely damaged or deformation on their embankment.
