Numerical Simulation of Seepage Field of Tailing Water Channel in Construction Period of Coupling Fields of Stress and Seepage

Advanced Materials Research, 2014
On the basic of rock and soil mass mathematic model, with the boundary conditions of classic section, the seepage field in construction period is simulated. Some conclusions are drawn: the hydraulic gradient of the channel slope where the seepage spills out exceeds the allowable hydraulic gradient and some engineering measures are needed to avoid ...

Initial Seepage Field FM Analysis

Advanced Materials Research, 2012
The initial seepage field analysis is prerequisite and important content for the water-tight underground cavern design. Although the field water pressure test can provide a more accurate isotropic permeability coefficient，which does not reflect the anisotropy permeability of jointed rock mass.Based on joins network simulation technique，a new method for

Site Evaluation and Design of Seepage Fields

Journal of the Environmental Engineering Division, 1974
A reevaluation of previous work by others indicated that soil can absorb septic tank effluent indefinitely if the application rate is kept below a certain level, which is a function of soil permeability. This long-term acceptance rate is independent of whether the soil is continuously or intermittently flooded, and varies from approximately 0.3 gpd/sq ...

Field investigations of seepage on existing dams

Hydrotechnical Construction, 1967
1. The successful operation of hydraulic structures erected on foundations which were previously considered unsuitable for the construction of large dams shows that with a properly functioning control of seepage under field conditions bolder engineering solutions are fully justified. 2.

Electric field during seepage of grout

Journal of Mining Science, 1995
1. The value of the γ potential occurring as a result of sorption of ions of the mineralized solution by the filtering medium in the form of a fractured rock mass is tens of mV and depends more on the structure of the rock and less on the concentration and composition of the solution. 2. In the case of plane-radial flow of the solution the distribution

Analysis of the Influence of Anisotropy on Seepage Field

Applied Mechanics and Materials, 2013
The anisotropy in the dam designs is a very important factor. In order to research the influence of anisotropy on seepage field of Dalong water control dam, this paper uses the three-dimensional finite element method to analyze the seepage characteristics and evaluate the safety of the dam by comparing the change characteristics of the pore pressure ...

Study on Unstable Seepage Field Characteristic and Seepage Control Measures of Wutagou Floodway

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
According to the basic theory of the saturated - non-saturated unsteady seepage field, the finite element model of Wutagou floodway is built by using the equivalent continuum model to analyze seepage characteristics and seepage failure conditions of the embankment and the surrounding soil.

Analysis on Seepage Field and Seepage Control Measure around Kunlong Hydropower Project

Applied Mechanics and Materials, 2013
The Kunlong Hydropower has high water head and complex geologic environment. It is necessary to study the seepage field and the seepage control measure. In order to set up a three dimensional seepage numerical model around the dam site, double fracture seepage systems contained main fractures network and fractured rock masses is adopted.

Field Solutions for Turbulent Seepage Flow

Journal of the Soil Mechanics and Foundations Division, 1971
A finite element solution is presented for obtaining field solutions for turbulent flow in porous media. Such problems are frequently of the free surface type. They are associated with rockfill dams and flood diversion, and with some natural slopes. Comparisons are drawn between laminar and turbulent states; the latter is shown to produce higher pore ...
