A uniaxial compression test is a laboratory test used to determine the compressive strength and deformation behavior of a rock or soil sample under a single axis of compression. This test is significant in rock mechanics and engineering geology for evaluating the mechanical properties of rocks, the stability of slopes and tunnels, and the design of foundations.
