Evaluation and Rehabilitation of the Seepage Problems at the Fengman Dam
نویسندگان
چکیده
Based on geological information of the Fengman dam, the seepage flow of the dam is analyzed. There are many different affecting factors on seepage problem, for example: the effect of the parameter of concrete, cut-off wall, the permeability coefficient of cut-off wall, drainage hole and grout curtains etc. On the basis of the research, the seepage control mechanism and effectiveness of the seepage control system with seepage prevention structures were studied in detail. Comparing effect of different factors on the wet surface, water leakage of the dam and uplift pressure of cut-off wall before and after reinforcement, and considering the overall engineering and social–economical importance of the Fengman dam, some additional treatment and reinforcement measures are recommended in this paper.

متن کاملEvaluation of seismic responses of earth dams in the steady-state seepage (a case study: Shamil Dam)
Considering the high seismic potential in most parts of Iran, the importance of studying the behavior of earth dams under earthquake loading, especially in the southern regions, is very important due to the number of these dams and seismicity of the Zagros mountain range. In recent years, many studies have been performed on the effects of earthquakes on earth dams, but these structures exhibit ...
متن کاملNumerical Simulation of Seepage Flow through Dam Foundation Using Smooth Particle Hydrodynamics Method (RESEARCH NOTE)
In this paper, a mesh-free approach called smooth particle hydrodynamics (SPH) is proposed to analyze the seepage problem in porous media. In this method, computational domain is discredited by some nodes, and there is no need for background mesh; therefore, it is a truly meshless method. The method was applied to analyze seepage flow through a concrete dam foundation. Using the SPH method, the...
متن کاملAssessment of water leakage through the right abutment of the Seymareh dam
One of the major issues in dam construction is water seepage, post impounding. Assessment and prediction of the amount of waterleakage can be useful in preventing such events. The Seymareh dam has been constructed on the Seymareh River in Ilam province,Southwest of Iran. The dam controls the floods and generates hydroelectric power. It is already under impoundment and the seepageproblem is bein...
