Also, these empirical models have been developed utilizing results of numerical modelling. In addition, the available empirical models to estimate the Slc have been developed using either classical regression analysis or multivariate adaptive regression splines and such techniques produce complicated models. However, prediction of the Slc is not straightforward process and it requires advanced soil models and calibrated soil parameters that are not readily available for designers/practitioners. In addition, and by analytical approach SLOPE/W (a sub-program of the Geo-Studio software) are used to assess the stability of the downstream slope and calculation factor of safety.Īccurate prediction of the liquefaction-induced settlement (Slc) is an essential requirement for a good design of buildings resting on liquefiable ground and subjected to seismic shake. A set of solutions checked by using the Geo-Studio software has been suggested in this research to solve this problem. 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 Seeing it becomes untradeable once you equip it I'm guessing you don't have to be in combat for it to degrade.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. Interesting, on the wiki page it says 'full degradation takes 10 hours' but it doesn't say whether that's only in combat or not. The seismic weapons work in the same way as other degradeable weapons - as soon as they start to degrade, they are untradeable until repaired." "Note that the tectonic armour cannot be traded once it has been equipped. Since Jagex have said that this new armour becomes untradable as soon as you equip it makes me think it has a timed lifespan and not a damage use one like virtus. Old pvp armours like vesta's decay after 60 minutes of wearing it, not from use, which is why it becomes untradable the moment you put it on. It will only degrade in combat, just like all the others of its kind I think it will eventually drop below virtus and stay there. K ratos wrote: Will they only degrde in combat? Because if not I think the price will stay higher simply because people like to show off nice armours
