摘要：

In underground excavation conditions, rock often undergoes very complicated loading and unloading process. However, in laboratory tests on rock, such as normal triaxial test, the loads are usually exerted gradually and continuously, which cannot simulate the real stress state of rock precisely. The test data of triaxial test of red sandstone under different loading paths are presented and the impact of different loading path on the deformation of rock samples is analyzed. Unlike the test results under normal triaxial procedures, the deformation of rock under different loading paths has nonlinear properties.
