The Cyclic Triaxial Evaluating System is a hydraulically operated loading frame with a different diameter triaxial cell appropriate for laboratory testing with large particle sizes, like railroad ballast. The system is capable of performing advanced triaxial tests typically associated with a cyclic triaxial system, including monotonic (static) and dynamic triaxial testing. What is the principal? When it is necessary to assess the strength and deformation characteristics of soils under cyclic loading conditions, dynamic triaxial testing is carried out on the soils. Dynamic loading from earthquakes, passing cars and trains, wind, waves, vibration machines, and other factors are examples of these circumstances. Dynamic triaxial tests come in a variety of forms, and the user should choose the one that most closely resembles the field conditions. What are the benefits? Flexible system capacity allows for the selection of specimen size, load, and pressure to meet budget and specification requirements. Interchangeable (internal submersible) load cells are provided with ranges of 8, 16, 25, 32, 64, 128 and 250 kN to accommodate extremely soft to very stiff soils. An external load cell is included with the load frame to match the model’s maximum load range of 250 kN. Direct, closed-loop skill that enables displacements or axial force on a sinusoidal, triangular, or custom waveform at 10 Hz: possibilities for precise and adaptable control. Automated cyclic triaxial system equipment What is an automated cyclic triaxial system?
In a single, adaptable unit, the cyclic triaxial system fully automates both cyclic and static triaxial testing. The system does not require additional air sacs, vacuum pumps, and wall-mounted components that consume valuable lab space and demand more maintenance because it simply has three major parts. The quickest response time is provided by a sophisticated, high-performance linear actuator with a low inertia servo driving system. For the most precise and reproducible outcomes, this is paired with a high-resolution feedback controller (closed loop and adaptive). Users can add their compressive strength test to the system at a minimal cost to maximise their investment thanks to the benefit of a fully operational load frame. The features are as follows:
shortens the testing period Conduct tests on samples that are isotropic, anisotropic, and Ko consolidated. Choose between 10 and 500 readings per second for the number of data points logged per cycle. Lower test failure rates and better quality assurance Benefits are as follows: doesn’t call for hydraulic oil does not employ any high-pressure systems that could be dangerous (3000 psi hydraulic fluid) very small, noiseless, portable, and switchable to static triaxial Customized high-performance linear actuator Low inertia, 1.8 kW peak servo-drive system for quick reaction A high-resolution feedback system for accurate and precise load and displacement control Continuous load moving at velocities greater than 200 mm/sec (8 in/sec) Self-sufficient and upkeep-free 50 Hz, single phase, 220 VAC (international)
What is it? The stability of a planet’s surface and rock-fill dams, earthworks, excavated slopes, and naturally occurring slopes in soil and rock can be assessed using slope stability analysis, which can be static or dynamic, analytical or empirical. The ability of sloped soil or rock slopes to endure or experience movement is referred to as “slope stability.” In the fields of engineering geology, geotechnical engineering, and soil mechanics, the stability condition of slopes is a topic of study and inquiry. Analyses typically try to comprehend the causes of a slope failure that has already occurred or the elements that could potentially cause a slope movement that results in a landslide. They also aim to prevent the onset of such a movement by taking mitigation steps to delay or stop it. 2D slope stability study that can take into account reinforcing materials including geotextiles, soil nails, and rock bolts. Slope gives civil and geotechnical engineers the capacity to examine and verify their projects that involve slope stability evaluations. Cuttings for permanent works, for instance, are a crucial component of linear infrastructure design. Why do you need it? Oasys Slope offers a validated, reliable, and user-friendly method of calculations, ensuring that acceptable and appropriate QA and QC standards are met. Civil and geotechnical engineers who are in charge of researching the global stability of reinforced earth structures, cuttings, and other structures use it. Analysis process Utilizing the “slices” approach (limit equilibrium), Oasys Slope analyses the two-dimensional slope stability and displays the findings in an easy-to-understand graphical style. Users can easily use partial factors, such as EC7. A finite element steady state seepage analysis or a specified pore pressure distribution are both options for slope. The impact of soil reinforcement on the ensuing safety factors and, consequently, the design can be considered. The benefits are as follows:
automatically and remotely gathers data from in-place instrument data loggers.
A system scheduler automatically generates, sends, and archives the necessary reports.
Responses to automatic SMS, email, or AAA alarms are logged using a dynamic online log.
To generate appropriate AAA lines, you must have a range of AAA values for different heights on deflection; a simplified vertical line is not acceptable.
Import design predictions and display the evolution of motions over time in comparison to projected behaviour.
Check the status of any instrument’s operation at any moment.
Readings, structural components, and geological data are combined in 3D modelling.
Create a sectional view that includes the observed lateral movement, water table, anchoring tension, and wall settlement.
Construction progress can be monitored with configured shift reports.
For general construction management and auditing, define each individual soil nail or anchoring component and combine them into a group.
