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 in particular relates to a method for obtaining a hole wall rock mass structural surface image and describing the three-dimensional roughness of the rock mass structural surface by using a drilling camera technology. This method can well describe the three-dimensional roughness information of rock mass structural planes, and solves the difficult problem of obtaining three-dimensional roughness information of deep rock mass structural planes. Background technique

[0002] With the rapid development of economic construction, the living space of the earth in the traditional sense can no longer meet the needs of human activities, and seeking development and living space deep in the earth has become a common trend in geotechnical engineering construction and development worldwide. In recent years, the state has paid more and more attention to the use of three-di...
