Description

technical field [0001] The invention belongs to the technical field of dam body model tests, in particular to a tailings dam model test box based on freeze-thaw cycles. Background technique [0002] The tailings dam model dam freeze-thaw cycle test box is an important test device for testing the stability of the tailings dam under the freeze-thaw cycle, and it is particularly important in the stability research of tailings dams in high-latitude mining areas . [0003] In the design of the tailings dam model test chamber under the action of freeze-thaw cycles, there are several key requirements that need to be met: (1) good sealing to ensure the independence of the test space; (2) accurate temperature simulation, Ensure the consistency of the ambient temperature changes during the test and the actual working conditions; (3) Ensure that the top surface of the model dam body is the main surface of temperature during the test process; (4) Ensure that the model dam body is place...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing tailings dam model freeze-thaw cycle test chamber has the following shortcomings: (1) The temperature fitting effect is poor, and it cannot meet the gradient temperature control form, which is far from the actual working conditions; (2) ) The placement of the test model dam body lacks automatic control and is easily affected by human factors; (3) The data acquisition system is separated from the test box and lacks integration, which increases the number of test personnel and reduces work efficiency
