The shear strength determined from the test expressed in terms of total stresses undrained conditions or effective stresses drained conditions is commonly used in embankment stability analyses, earth pressure calculations, and foundation design.

The shear strength of a saturated soil in triaxial compression depends on the stresses applied, time of consolidation, strain rate, and the stress history experienced by the soil. Triaxial cells for advanced applications The cell essentially consists of a trasparent banded chamber to prevent excessive expansion during the test and to protect against explosive failure when used with compressed air systems.

TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories to perform high quality tests at. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies or any consideration of end use.

Note 2—Notwithstanding the statements on precision and bias contained in this test method. Template for data processing and reporting: Historical Version s – view previous versions of standard.

The inch-pound units given in parentheses are mathematical conversions which are provided for information purposes only and are not considered standard.

With this equipment it is possible to perform the consolidation stage of three triaxial specimens at the same time for CU and CD tests in anisotropic conditions. Maintenance Spares Technical trainings Warranty Academy. Installed on a PC communicating with the system over a fast Ethernet connection, the software can be used to configure the system scalibrate transducers, specify test parameters, set Data acquisition can be shared with other soil testing equipment.

Agencies which meet the criteria of Practice D are generally considered capable of competent testing.

ASTM D Standard

Generally, three specimens are tested at different effective consolidation stresses to define a strength envelope. Data acquisition is included in the load frame; four channels are available for load, d4776, pore pressure and volume change. In this standard density is given only in SI units.

Reliable testing depends on several factors; Practice D provides a means of evaluating some of those factors. This shear strength may be applied to field conditions where full drainage can occur drained conditions or where pore pressures induced by loading can be estimated, and the field stress conditions are similar to those in the test method.

More than system configurations are available depending on type of test, sample size, pressure system. EmS technology is environmentally friendly and clean to operate, requiring no compressed air or hydraulic oil. Home Products Search results Results for: A typical c4767 triaxial system with built-in acquisition measurement includes: Three or six simple thumbscrew are used to clamp the upper part of the cell to the base, which make assembly and disassembly a very quick and Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part astmm the standard.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

Triaxial cell with accessories: TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that want to perform high quality tests at.

Consolidation bench for triaxial cells The apparatus has been designed to reduce the testing time for triaxial tests, where only one compression machine is available. Please contact us for a complete offer.

Standard triaxial configuration with built-in data acquisition can be used for performing additional tests such as CBR, Unconfined and CRS. In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. X4767 addition, they are representative of the significant digits that generally should be retained.

Note 1—If the strength is required for the case where the soil is not consolidated during testing prior to shear, refer to Test Method D or Test Method D Soil mechanics – Consolidation benches: Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method.

Soil mechanics – Static triaxial systems: Specimens are isotropically consolidated and sheared in compression without drainage at a constant rate of axial deformation strain controlled. In this test method, the shear characteristics are measured under undrained conditions and is applicable to field conditions where soils that have been fully consolidated under one set of stresses are subjected to a change in stress without time for further consolidation to take place undrained conditionand the field stress conditions are similar to those in the test method.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that perform high quality tests at high productivity levels.

Data are automatically transferred to the PC in real time for live plotting and monitoring of the tests atsm progress. A typical standard triaxial system with external data acquisition system includes: A typical Standard triaxial system with analogue measurements includes: The load frame is built around a robust twin column It is beyond the scope of this test method to consider significant digits used in analysis methods for engineering design.

Standard triaxial configuration with external data acquisition can be used for performing additional test such d47677 CBR, Unconfined and CRS, Permeability.
