| Abstract: | In order to explore the physical and mechanical properties of rocks in depth,this paper selects red sandstone as the test material,takes the number of freeze-thaw cycles and confining pressure as the research indicators,and explores the influence of these two indicators on the rock properties through the design of experiments about testing influencing factors.The test results show that the confining pressure and the number of freeze-thaw cycles have a great impact on the triaxial compressive strength and elastic modulus of the rock,while the mechanical properties have changed significantly. |
