内容記述 | Experimental study of the mechanical properties of rocks underhigh pressure and temperature is very helpful for making clearthe mechanical behavior of the earth's crust and various phenomenaoriginating from the earth's crust. Although much experimentalwork has been made, available data is still insufficient for a generaldiscussion of the behavior of the various rocks from the geophysical point of view. In this series of experimental work, the effect ofconfining pressure on the deformation and fracture of different types of rocks are systematically investigated. In this paper, the results of triaxial compression tests on twelve dry rocks, including diorite, granite, andesite, trachyte, tuff, sandstone and marble, are described. The confining pressure ranges from 1 to 1500 atmospheres. The stress-strain curves and curves for the breaking or yielding strength and the degree of the strain hardening as functions of confining pressure are given for each rock. The compact igneous rocks are very brittle and their breaking strength increases with the confining pressure.
