Abstract
A loading apparatus for rock fracturing simulation includes an upper cover plate, a lower cover plate, lateral pressure pieces, and an acoustic measurement module top pillar. There are at least two lateral pressure pieces which are provided with a force applying face respectively for transmitting a radial force to a core sample. The upper cover plate, the lower cover plate and the lateral pressure pieces enclose a loading space for placing the core sample, and the lateral pressure pieces can slide along a radial direction of the core sample and relative to the upper cover plate or the lower cover plate. The lateral pressure pieces are provided with a sensor inserting hole for allowing a sensor to pass through respectively, and the sensor is attached to an outer peripheral wall of the core sample.
