Rock mechanical parameter automatic acquisition method, apparatus and device, and storage medium

The invention provides a rock mechanical parameter automatic acquisition method, device and equipment and a storage medium. The method comprises the following steps: reading stress-strain data obtained based on a rock uniaxial compression experiment; performing data interpolation on the stress-strain data to form a stress-strain curve; taking a target point on the stress-strain curve as a starting point, and dynamically extending to the two ends of the stress-strain curve until the goodness of fit of a regression straight line formed by the current extension is lower than a set threshold value; segmenting the stress-strain curve by taking a stress peak point and a strain peak point on the stress-strain curve and an end point of the regression straight line as segmentation points; calling a first rock mechanical parameter calculation module to process the stress-strain curve to obtain a first type of rock mechanical parameters; a second rock mechanical parameter calculation module is called to process the segm
