AI Technical Summary
Existing methods for preparing jointed rock samples cannot accurately simulate the joint characteristics in real rock masses, leading to errors in the study of rock mechanical properties. Furthermore, the heterogeneous materials or processing techniques used in traditional methods cannot reflect the true mechanical properties of rocks.
An endogenous jointed rock sample preparation device and method based on electric pulse directional fracturing was adopted. By combining the jointed rock sample casting mold with the directional fracturing container and high voltage electric pulse directional fracturing technology, a natural rough joint surface with the same material as the rock was formed.
It enables precise preparation of jointed rock samples, reduces errors, and ensures that the joint surfaces are consistent with the rock material and have the same mechanical properties, thus more accurately reflecting the mechanical characteristics of the rock. This is suitable for in-depth research on rock mass failure mechanisms and optimization of engineering design.
