TL;DR: In this article, a stability analysis carried out on 21 m high Bhimdi earth dam was performed by changing different parameters such as changing berm width, changing position of filter drains and to gain desire stability how much strengthening required that was carried out by using software Geo-studio.
Abstract: Slope stability analysis of earth dam is very important to ascertain the stability of the structure. The stability of earth dam depends on its geometry, its components, materials, properties of each component and the forces to which it is subjected. The design of earth dams involves many considerations that must be examined before initiating detailed stability analyses. Such as geological and subsurface explorations, the earth and/or rock-fill materials available for construction should be carefully studied. This paper presents stability analysis carried out on 21 m high “Bhimdi earth dam” situated near Tq. Warud Dist. Amravati (Maharashtra State) by changing different parameters such as changing berm width, changing position of filter drains and to gain desire stability how much strengthening required that was carried out by using software Geo-studio. The Existing design results are compared with the simulated results obtained from software

TL;DR: In this paper, the authors used the finite element method to solve the governing equations of flow through earth dams and the computer program Geo-Slope is used in the analysis through its subprogram named SEEP/W.
Abstract: Seepage analysis of earth dams is one of the major interesting points in geotechnical engineering. The amount of water seeping through and under an earth dam together with the distribution of the water pressure can be estimated by using the theory of flow through porous media which is one of the most valuable analytical tools available to the engineer. In this paper, the finite element method is utilized to solve the governing equations of flow through earth dams. The computer program Geo-Slope is used in the analysis through its sub-program named SEEP/W. Eight node isoparametric elements are used to model the dam and its foundation, while mapped infinite elements are used to model the problem boundaries. A case study is considered to be Al-Adhaim dam which consists of zoned embankment 3.1 km long. The dam at its actual design is analyzed using the program SEEP/W. Then several analyses are carried out to study the control of seepage in the dam through studying the effect of several parameters including the permeability of the shell material and the presence of impervious core and its location and thickness. It was concluded that the presence of clay core has an important effect on decreasing the exit gradient, which may increase in the order of 300% when the core does not exist and the factor of safety may be critical when the water level in the reservoir is at 143.5 m. The sloping core of Al-Adhaim dam is the best design for core than other choices since it permits the lowest values of seepage and provides the lowest exit gradients.

TL;DR: In this paper, the authors used the SEEP/W program to compute seepage and slope stability analysis of Hub dam (earthen dam) by using the slave programs of Geo-Slope software.
Abstract: The present research work was conducted to compute seepage and slope stability analysis of Hub dam (earthen dam) by using the slave programs of Geo-Slope software i.e. SEEP/W and SLOPE/W respectively. The simulation results obtained from the SEEP/W program revealed that the average flow rate of seepage at maximum, normal and minimum pond level were 5.728 x 10-4 (ft3/sec/ft), 4.988 x 10-4 (ft3/sec/ft), and 4.513 x 10-5 (ft3/sec/ft) respectively. The exit gradient value in all different pond levels was less than 1.0, and maximum seepage velocity is within permissible limits, which implies that the dam is secure against piping for the entire scenarios. SLOPE/W program was used to analyze static slope stability of embankment slope under various loading conditions. The stability of embankment slopes was checked by four different analysis methods i.e. Bishop, Janbu, Ordinary method of slice and Morgenstern-Price method accordingly. The simulation results revealed that upstream and downstream side of the dam section has a direct effect on the factor of safety. The three different loading cases were analyzed i.e. end of construction (upstream and downstream slope), steady state seepage (downstream slope) at maximum water level at EL 346 ft, and rapid drawdown for (upstream slope) with the minimum factor of safety 1.653, 1.911, 1.634 and 1.766 respectively. From the results achieved, thus it can be concluded that the Hub dam is safe against the danger of piping and slope failure.

TL;DR: In this article, the effects of berm properties on a moderate height earthen dam stability were investigated by analyzing the seepage through the dam and the slopes' stability under steady-state, rapid fill and rapid drawdown conditions with the finite element method.
Abstract: This study investigates the effects of berm properties on a moderate height earthen dam stability. The impacts of different berm heights, numbers and widths on the safety of the Hancagiz Dam are determined by analyzing the seepage through the dam and the slopes’ stability under steady-state, rapid fill and rapid drawdown conditions with the finite-element method. The results showed that increasing the upstream berm height, number, or width of berms provides higher safety factors for the upstream slope. However, an excessive increase in the berm height is seen to cause a lower safety factor. Increasing the berm number is found to give maximum stability among all options. Any change made on the upstream berm does not affect the safety of the downstream slope.

TL;DR: In this article, the authors used geotechnical software for analysis of slope stability, including seepage in both saturated and unsaturated areas, in both unsaturated and saturated areas.
Abstract: Analyzing the stability of earth structures is the oldest type of numerical analysis in geotechnical engineering. The idea of discretizing a potential sliding mass into slices was introduced early in the 20th Century. Even to this day, stability analyses are by far the most common type of numerical analysis in geotechnical engineering. This is in part because stability is obviously a key issue in any project – will the structure remain stable or collapse? This, however, is not the only reason. Concepts associated with the method of slices are not difficult to grasp and the techniques are rather easy to implement in computer software – the simpler methods can even be done on a spreadsheet. Consequently, slope stability software became available soon after the advent of computers. In this study, we use “GEOSTUDIO” Software for analysis of slope stability, seepage in both saturated and unsaturated
