construction of asphaltic core dams is a relatively novel method especially in iran. iran is located in a region with high seismicity risk. therefore, many researchers have focused on the behavior of such types of dams under earthquake loading. in this research, the behavior of asphaltic core rockfill dams (acrd) has been studied under earthquake loading using nonlinear dynamic analysis method ...

The equations for the earthquake forces on a rigid dam with an inclined upstream face of constant slope are solved exactly by two-dimensional potential-flow theory. The distribution of the hydrodynamic pressure along the upstream face and the total horizontal, vertical and normal loads on the dam are computed from the integral solutions. The results obtained from the exact theory are compared w...

The design of arch dams usually involves a prolonged process of successive trial and error redefinitions. The current computer technology however enables to automate this task, in order to achieve the most economic solution overall. In the paper, the implemented optimization method of the geometry of concrete arch dams is presented as well as case studies of its application in the design of two...

The configuration and safety factor of rockfill dams design depend on materials used in construction the dam. In some regions, available for using as impermeable element dam body are dispersive it is inevitable to consider dispersivity material construction. Internal erosion through cracks or other openings embankment most concern soils. authors have designed an by soil East Africa after finali...

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 seep...
