Abstract

For the purpose of research on behavior of argillaceous dolomite suffering from extreme weather impacts in Guizhou region, Study the behavior of the physical properties of rock samples after the water phase transition effect. By wet and dry cycle test, freeze-thaw cycle test, wet freeze-thaw cycle test on rock samples, studying the longitudinal wave velocity, the macro scale and quality parameters of the rock samples after each cycle, while observing the appearance of the rock sample characteristics, and explaining the reason for the parameters change of the rocks macroscopic properties from the microscopic. The results show that in the water phase-change cycle (wet and dry cycle test, freeze-thaw cycle test, wet freeze-thaw cycle test) process, the rock sample degradation forms performance for chipping, flaking mode, longitudinal wave velocity decreases obviously, and Longitudinal wave velocity decreased respectively by 18.01%, 14.88% and 17.05% on average, while mass has a small increase, maximum change rate of 0.5%. Macroscopic properties of the rock are significantly affected by water phase-change cycle.
