Study on mechanism of seepage drainage facilities affecting saturated-unsaturated seepage flow field of high tailings dam

On the physics of unstable infiltration, seepage, and gravity drainage in partially saturated tuffs.

To improve understanding of the physics of dynamic instabilities in unsaturated flow processes within the Paintbrush nonwelded unit (PTn) and the middle nonlithophysal portion of the Topopah Spring welded tuff unit (TSw) of Yucca Mountain, we analyzed data from a series of infiltration tests carried out at two sites (Alcove 4 and Alcove 6) in the Exploratory Studies Facility (ESF), using analyt...

Numerical 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...

Transient seepage model for saturated-unsaturated soil systems: a geotechnical engineering approach

A two-dimensional finite element model is proposed to simulate transient seepage for complex groundwater flow systems. The complete soil system is treated as a continuum encompassing flow in both saturated and unsaturated zones. In the unsaturated zone, the air phase is assumed to be continuous and open to atmospheric pressure. The coefficient of permeability of the unsaturated soil is assumed ...

Numerical Analysis of the Seepage - Deformation in Unsaturated

The Effect of Cut-off Wall on Seepage and Uplift Pressure under Earth Dam (Case Study: Shamil Dam in Iran)

Design of earth dams and their problems are important during construction and after it,because of their potential hazards and failure for downstream population. The dam foundation seepage control the the importance from the perspective of a major engineering project and explain the economic performance of each project is allocated. among activities that can be used to prevent piping phenomena a...
