Abstract

The embodiment of the invention discloses a tectonic stress direction prediction method and device, terminal equipment and a storage medium, belongs to the technical field of engineering investigation and design, and can solve the problem of low test success rate in tectonic stress direction prediction in the prior art. The method comprises the following steps: performing an ultrasonic imaging test on a drilled hole to obtain rock mass ultrasonic imaging data of the drilled hole; rock mass joint information of the drill hole is obtained from rock mass ultrasonic imaging data; drawing a joint trend rose diagram according to the rock mass joint information; and based on the Anderson stress theory, the tectonic stress direction of the position where the drill hole is located is determined according to a joint trend rose diagram.

Description

technical field [0001] The present application relates to the technical field of engineering survey and design, and in particular to a method, device, terminal equipment and storage medium for predicting the direction of structural stress. Background technique [0002] At present, in the field of engineering survey and design technology, tectonic stress is one of the important factors that cause the deformation of weak rock mass and the risk of rockburst. 1. In the construction of large dam foundations, it is necessary to measure the structural stress. Existing methods for predicting the direction of structural stress usually use hydraulic fracturing, first testing the direction of structural stress in each borehole, and then predicting the direction of regional structural stress based on the obtained direction of structural stress at a single point. [0003] However, the above-mentioned structural stress direction prediction method has the following problems: the structura...
