Abstract: A strength measurement system for rock specimen under microwave effect includes a supporting device, a testing cabin, a strength test device, a hydraulic loading device and a microwave transmitting device. Testing cabin is arranged on supporting device; strength test device is arranged in testing cabin, and a rock specimen is arranged on strength test device; a fixed end of hydraulic loading device is arranged on supporting device, and a movable end of hydraulic loading device acts on rock specimen; microwave transmitting device is arranged on testing cabin, and microwave transmitting device acts on rock specimen. Testing cabin has isolation function and limits microwave within testing cabin. By loading microwave on rock specimen by means of microwave transmitting device, effect of microwave on rock strength is learnt, and correlation between power and duration of microwave on rock specimen and rock strength is studied in targeted manner.

Abstract: A system and method for measuring rock volume change under microwave irradiation. The system includes a test cavity, a microwave control device, strain measurement devices, a measurement circuit, and a resistance strain gauge. The test cavity is of a sealed cavity structure, in which a rock specimen and the microwave control device are provided. The strain measurement device includes circumferential strain gauges and axial strain gauges, and is attached to the surface of the rock specimen. The measurement circuit is connected to the strain measurement devices by means of leads, and the resistance strain gauge. After microwaves emitted by the microwave control device act on the rock specimen, the plurality of circumferential strain gauges and the axial strain gauges collect data from the rock specimen, and the volume change of the rock specimen can be obtained in combination with the measurement circuit and the resistance strain gauge.

Abstract: A system and a method for measuring the volume change of rock under the action of microwaves are disclosed. The test cavity is of a sealed cavity structure, and a rock specimen is placed in the test cavity. The microwave control device is arranged inside the test cavity. The strain measuring device includes circumferential strain gauge and axial strain gauge and is attached to the surface of the rock specimen. The measurement circuit is connected with a number of strain measuring devices through lead wires, and the resistance strain gauge is connected with the measurement circuit. After the microwaves emitted by the microwave control device act on the rock specimen, data acquisition is carried out on the rock specimen through the number of circumferential strain gauges and the number of axial strain gauges which are attached to the surface of the rock specimen.
