Abstract

The invention discloses a rock fracture seepage-temperature coupling visual test system and a test method. The system comprises a water storage tank, a water pump, a liquid preheater, a constant temperature box, a transmission cross flow pipe, a liquid radiator, a data acquisition device and a rock fracture sample; the rock fracture sample is arranged in the constant-temperature box, the two transmission cross-flow pipes are arranged at the two ends of the rock fracture sample respectively, and each transmission cross-flow pipe is internally provided with a pressure sensor and a first temperature sensor which are used for measuring parameters of liquid passing therethrough; a plurality of second temperature sensors for monitoring rock temperature change are arranged on the upper and lower surfaces of the rock fracture sample; According to the invevntion, the water flow with a set temperature is supplied through the liquid preheater, and the constant temperature of the rock fracture sample is kept through the constant temperature box, so that the rock fracture seepage-temperature coupling test is carried out. The device is simple in structure, convenient to install and easy to operate; the equipment precision is high, and the measurement error is controllable; besides, the seepage law of multiple groups of samples at high temperature can be continuously measured and researched.

Description

technical field [0001] The invention belongs to the technical field of rock mechanics tests, and in particular relates to a visual test system and test method for rock fissure seepage-temperature coupling. It is suitable for seepage and heat transfer test research under high temperature conditions of dense rocks such as sandstone, granite and artificial materials such as concrete involved in civil engineering, water conservancy, tunneling, geothermal mining and mining engineering. Background technique [0002] Most of the deep high-temperature geothermal rock bodies are granite, and a small part of sandstone. In the deep rock mass, the in-situ stress is large and the temperature is high, and the environment of the hot dry rock mass (4km-5km) can reach above 300°C. [0003] 1 Assessment and prevention of geological disasters: [0004] The physical and mechanical properties of fractured rock mass will be weakened by the influence of geothermal heat, and the seepage of fractu...
