System and method for testing rock fracture under vacuum and extreme-temperature condition

A system for testing rock fracture under a vacuum and extreme-temperature condition, comprising:

• a vacuum extreme-temperature loading structure;
• an overall loading frame structure;
• and
• a mobile cart;
• wherein the vacuum extreme-temperature loading structure comprises a vacuum transparent shield, a vacuum base, and an extreme-temperature loading module;
• a bottom end of the vacuum transparent shield is covered on the vacuum base and is hermetically connected with the vacuum base to form a vacuum structure;
• and the extreme-temperature loading module is provided inside the vacuum structure;
• the overall loading frame structure comprises an overall frame and a loading cylinder;
• a middle of the overall frame is provided with a loading space, and the vacuum extreme-temperature loading structure is located in the loading space;
• a center of a top end of the overall frame is provided with a first loading through hole, and the loading cylinder is located above the first loading through hole to enable a loading rod of the loading cylinder to pass through the first loading through hole to apply a loading force to the extreme-temperature loading module;
• an end of the loading cylinder is fixedly connected with the overall frame;
• and
• the mobile cart is located in the loading space and is slidably connected with the overall frame, and the vacuum base is arranged on the mobile cart.
