Abstract

An RQDt anisotropy solving method based on photogrammetry, RQD and an optimal threshold belongs to the field of RQDt anisotropy solving, and comprises the following steps: (1) quickly acquiring structural plane digital photogrammetry; (2) drawing a structural surface pole diagram and a trend rose diagram; (3) making rock mass quality calculation based on RQD indexes; (4) generating and sectioninga rock mass three-dimensional fracture network model; (5) drawing an RQDt anisotropy diagram; (6) arranging an optimal threshold t solving method based on RQD inversion; and (7) arranging an RQDt anisotropy solving method. Photogrammetry, fuzzy equivalent clustering, an RQD theory, a fracture network model, a generalized RQD theory and inversion calculation are combined, the optimal threshold t and anisotropy of RQDt are solved, and the RQDt anisotropy solving method based on photogrammetry, RQD and the optimal threshold is provided. The method is clear, and is suitable for anisotropic solution of rock mass RQDt.

Description

technical field

[0001] The present invention relates to a RQD based on photogrammetry, RQD and optimal threshold t Anisotropy solution method, especially the present invention is based on photogrammetry, fuzzy equivalent clustering, RQD index, crack network model and generalized RQD theory, and calculates RQD by inversion t The range of optimal threshold t and the optimal threshold t value, gives the RQD t Anisotropic solution method, providing a RQD based on photogrammetry, RQD and optimal threshold t Anisotropic solution method, belonging to RQD t Anisotropic solution field. Background technique

[0002] In nature, anisotropy is ubiquitous. Rock masses exhibit very pronounced anisotropy, with properties that vary with viewing angle and measurement direction. The origin of rock anisotropy changes can be attributed to geological origin, such as unique bedding in sedimentary rocks, unique natural pores in basalt, gneiss structure in gneiss and cleavage in slate, and thro...
