Equivalent-linear analysis of earth dams with QUAD4 is a state-of-practice approach which incorporates a cumulative level of knowledge in soil dynamics that is still used today in many organizations. Nevertheless, today’s availability of more advanced nonlinear effective-stress analysis tools has improved significantly our estimates of shaking-induced permanent deformations of earth structures....

The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio State Department of Natural Resources (ODNR) issued new regulations in 1981 requiring that design flood for class I dams be considered equal to the Probable Maximum Flood (PMF). Flood routing studies performed...

The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The Bureau of Reclamation (Burec) determined that the dam and its foundation would be susceptible to liquefaction and failure during a potential earthquake; a series of contracts was let to remove and replace the d...

Analysis of seepage and stability is considered as an important case in designing which today, withadvanced numeric software acceptable results will be obtained before and after Construction. In thepresent study, the behavior of earth dam against effective factors was investigated by softwareAnsys12. The studied dam is Maroun soil dam, which is located in 19Km north of Behbehan andconstructed o...

The rockfill structures are widely constructed throughout the world and rockfills are largely used in these structures as main materials or filler materials. In the crust of earth dams, the rockfill materials role is to stabilize the body of the dam, however, the behavior of these materials in Particular their shear strength is not fully understood. In this study, different tests have been cond...

Generally seepage analysis and stress–strain analysis are conducted separately in the analysis of dams with varied water levels, which neglects the impact of soil deformation on seepage. The impact, however, is significant when the water level varies greatly. In this study, a simplified approach for consolidation analysis of unsaturated soil is used to conduct numerical simulations of water-fil...

How to accurately determine the mechanical parameters of rockfill is one of the key issues of concrete-face rockfill dams. Parameter back-analysis using internal or external monitoring data has been proven to be an efficient way to solve this problem. However, traditional internal or external monitoring methods have limitations in efficiency and long-term monitoring. In this paper, the displace...
