The invention relates to a line crack line segment-based fragmented structure rock mass fragmentation degree quantification method, and belongs to the field of fragmented structure rock mass. The method comprises the following steps: (1) acquiring structural surface geometrical characteristic parameters of the rock mass with the fragmented structure; (2) analyzing probability distribution and characteristic parameters of the geometric characteristics of the structural surface; (3) generating three-dimensional network data of the rock mass structural plane; (4) performing rock mass structural plane three-dimensional network visualization; (5) outputting a profile view; And (6) calculating a line crack index based on the line crack line segment. The method comprises the following steps: analyzing probability distribution and characteristic parameters of geometric characteristics of a structural surface according to the geometric characteristic parameters of the rock mass structural surface of a fragmented structure acquired on site, acquiring three-dimensional network data of the rock mass structural surface and realizing three-dimensional network visualization of the rock mass structural surface, and outputting an output profile view according to the rock mass structural plane three-dimensional network visualization result. And on the basis, establishing a line crack distribution function of the fractured rock mass, and representing the fragmentation degree of the fractured rock mass.
Description
technical field [0001] The invention relates to the field of fragmented rock mass, in particular to a method for quantifying the degree of fragmentation of a fragmented rock mass based on a line segment. Background technique [0002] Fractured structure rock mass is the worst type of engineering rock mass. Its structural planes are often connected and densely developed. The integrity and overall strength of the rock mass are low, showing strong heterogeneity, discontinuity, and anisotropy. and other features. At present, the classification and grading of fractured rock masses are mainly divided into three types according to their structural characteristics: mosaic fractured structure, layered fractured structure and fractured structure. This method is not enough to accurately quantify and distinguish the fractured rock masses with different degrees of fragmentation, which makes it difficult to carry out research on the mechanical properties and mechanical models of rock mas...
