Permeability test

- A test to determine movement through concrete of water under pressure.
- A procedure usually followed to determine the watertightness of the foundation and abutment rocks, as one phase of foundation test drilling done before the construction of dams. the test is performed by placing packer assemblies in diamond-drill holes to segregate each successive different stratum or each 5-foot depth, and water is injected into the borehole space between the packers with a high-pressure pump. the volume of water escaping into the rocks is a measure of the permeability, indicating the amount of water that will seep through the foundation or abutment of the dam and whether or not the dam foundation should be grouted.

Permeability, английский
- Perméabilité
- The ease with which a fluid flows through a porous material (wood) in response to pressure.
- A measure of the ease with which water penetrates a material.
- The relationship of flow per unit area to differential pressure across a filter medium.
- (of a membrane) the ability to allow some substances to pass through
- Проницаемость о ~ to heat теплопроницаемость ~ of soil проницаемость грунта air ~ воздухопроницаемость
- The state or quality of being penetrable by fluids or gases.
- The specific permeability, k (in m? ) is often referred to simply as
- The capacity of a solid substance (such as rock) to transmit a fluid. the degree of permeability depends on the number, size, and shape of the pores and/or fractures in the rock and their interconnections. it is measured by the time it takes a fluid of standard viscosity to move a given distance. the unit of permeability is the darcy.
- The capacity of a porous rock to transmit fluids.
- A measure of a material’s ability to align its magnetic domains in response to an applied magnetic field.
- A measure of the ease with which a fluid flows through the connecting pore spaces of rock or cement. the unit of measurement is the millidarcy.
Permeability, английский
Permeability (mt), английский
- The ease with which a magnetic field or flux can be set up in a magnetic circuit. it is not a constant value for a given material but is a ratio. at any given value of magnetizing force, permeability is b/h the ratio of flux density, b, to magnetizing force h.
- The ease with which a material can become magnetized. it is the relationship between field strength and the magnetizing force.
Permeability coefficient, английский
Permeability creation, английский
The action of various engineering techniques to create fluid pathways within rock, such as fracture enhancement or creation by hydraulic pressure or imposed temperature differential.

- Examen
- A check on the performance characteristics of a building component, device, material, piece of equipment, or system to determine its conformity with performance criteria and standards. tests may be performed in the prototype stage, during manufacture, at the site during and after installation, after the project’s completion, or at any combination of these times.

- Технические испытания
- To explore an unproved area by using boreholes to search for a mineral deposit, or to obtain samples of soil or rock from which the physical characteristics of the sampled formations can be determined, as in foundation testing.
- To determine the inclination of a borehole by means of an acid-dip survey.
- Испытание. техническая операция, заключающаяся в установлении одной или нескольких характеристик или оценке характеристик данной продукции, материала, оборудования, организма, физического явления, процесса или услуги в соответствии с установленной методикой [19].
- A measurement of fishing line strength. a higher test number equals more strength.
- The event of a price movement that approaches a support level or a resistance level established earlier by the market. a test is passed if prices do not go below the support or resistance level, and the test is failed if prices go on to new lows or highs.
