Abstract
The present disclosure provides a system for measuring dynamic physical properties of a rock, the system being configured to simulate various states of the rock under various pressure and temperature conditions, so as to facilitate the research on dynamically changing physical properties of the rock under those conditions, the system including: a kettle; a sample clamping device including a lower end rod and a fixed upper end rod, and a sample cavity disposed between the upper end rod and the lower end rod and located in the kettle; an overburden pressure device configured to drive the lower end rod to move up and down; a sample sheath configured to sleeve a sample of the rock located in the sample cavity, the sample sheath being contractible inwards under pressure; a confining pressure maintaining device configured to control a pressure in the kettle; and a heater configured to control a temperature in the kettle.
