Problems solved by technology

It can be seen from this that it is not accurate enough to use core data as the source of rock mass structural plane information. Therefore, it is necessary to propose an in-situ measurement technology to directly measure the structural plane on the borehole wall to obtain the Structural information

Abstract

The invention discloses a three-dimensional roughness description method for a rock mass structural surface based on borehole camera technology. The method comprises the steps of obtaining a hole walldeveloped panoramic view; obtaining the contour line of the lower wall surface of the rock mass structural surface; fitting a structural surface fitted line, and obtaining the reference plane of thelower wall surface of the rock mass structural surface, and the inclination orientation and the inclination angle of the rock mass structural surface; acquiring a contour line developed curve; acquiring a spliced contour line; obtaining the reference contour line of the set sampling length and the set sampling precision; according to the fractal dimension of each reference contour line segment, forming a structural surface roughness coefficient rose diagram and describing the three-dimensional roughness of the rock mass structural surface based on the same. The method can well describe the three-dimensional roughness information of the rock mass structural surface, and solves the problem that the three-dimensional roughness information of a deep rock mass structural surface is difficult toobtain.

Description

Technical field [0001] The invention belongs to the technical field of rock mass engineering and image recognition, and specifically relates to a method for acquiring an image of a rock mass structure surface of a hole wall by using a drilling camera technology and describing the three-dimensional roughness of the rock mass structure surface. This method can describe the three-dimensional roughness information of the rock mass structural surface well, and solves the difficult problem of obtaining the three-dimensional roughness information of the deep rock mass structural surface. Background technique [0002] With the rapid development of economic construction, the traditional living space on the earth can no longer meet the needs of human activities, and seeking development and living space in the deep part of the earth has become a common trend in geotechnical engineering construction and development worldwide. In recent years, the state has gradually paid attention to the use...
