Abstract
(EN)
A medium-low strain-based dynamic static integrated experimental test system, comprising: a specimen (101), heating plates (102), rigid press plates (103), acoustic emission sensors (104), static loading devices (201), a dynamic loading device (202), magnetostrictive displacement sensors (203), a specimen loading mechanism (204), and load sensors (205). Undercuts are designed in the rigid press plates (103) in six directions of the rock specimen (101). The undercuts in the rigid press plates (103) should be cylindrical, and the diameter thereof should be 2-4 cm. The acoustic emission sensors (104) are embedded into the rigid press plates (103) and analyze three-dimensional inner stress wave propagation features and three-dimensional anisotropy and heterogeneity of the rock specimen (101) by actively exciting and receiving ultrasonic waves.

L'invention concerne un système de test expérimental statique-dynamique intégré basé sur une contrainte moyenne-faible comprenant : un échantillon (101), des plaques chauffantes (102), des plaques de presse rigides (103), des capteurs d'émission acoustique (104), des dispositifs de charge statique (201), un dispositif de charge dynamique (202), des capteurs de déplacement magnétostrictifs (203), un mécanisme de chargement d'échantillon (204) et des capteurs de charge (205). Des gravures sous-jacentes sont formées dans les plaques de presse rigides (103) dans six directions de l'échantillon de roche (101). Les gravures sous-jacentes dans les plaques de presse rigides doivent être cylindriques, et leur diamètre doit être de 2 à 4 cm. Les capteurs d'émission acoustiques (104) sont intégrés dans les plaques de presse rigides (103) et analysent les caractéristiques de propagation d'ondes de contrainte interne tridimensionnelles ainsi que l'anisotropie et l'hétérogénéité tridimensionnelles de l'échantillon de roche (101) en excitant et en recevant activement des ondes ultrasonores.
