Rock multivariate information collection system and test method

Abstract

The invention discloses a rock multivariate information collection system and test method. The system comprises a loading mechanism, a monitoring mechanism and a protection device, wherein the loadingmechanism comprises a controller, a base, a pressure frame and a loading cone head; the monitoring mechanism comprises a pressure sensor, a displacement sensor, a camera, a CT scanning device and a sound emission sensor; data received by the sensor can be automatically transmitted to the PC end for data analysis and processing in real time; the pressure sensor and the displacement sensor can automatically record the rock test specimen deformation and stress during the loading; the CT scanning device can automatically scan the generation and the expansion of the rock test specimen cracks; thesound emission sensor automatically receives the sound emission signals and is used for determining the maximum stress previously received by the rock; the protection device is arranged on the outer periphery of the loading mechanism to achieve the protection effect. The rock multivariate information collection system can realize the automatic loading and automatic loading stopping; the measurement precision is high; information in multiple aspects can be collected; the generation and the expansion of the rock test specimen crack generation are analyzed; the real-time data recording analysis and visual effects can be realized.

Description

technical field [0001] The invention relates to a rock information collection device, in particular to a data processing method of a rock multi-element information collection system. Background technique [0002] In the study of rock mechanics, it is necessary to collect various physical parameter information of rocks, such as uniaxial saturated compressive strength, deformation modulus, etc. But at present, there are more or less difficulties in the collection of these information. Taking the test method of directly measuring the uniaxial saturated compressive strength of rock as an example, the current measurement method has low data accuracy and convenience of the test. Poor, the test process is relatively complicated, and there may be safety hazards such as rock debris falling out and hurting people during the test process. [0003] In the indirect determination of the uniaxial saturated compressive strength of rock samples, point load tests can be used to measure the p...

Problems solved by technology

However, the existing test equipment can measure too little information on the rock sample, and it is impossible to observe and analyze the crack formation and expansion process of the rock sample under the point load, and it is impossible to record and analyze the data in real time on the PC. Low
