Abstract

The invention belongs to the technical field of engineering exploration, relates to a rock mass integrity coefficient calculation method and device and a storage medium. The calculation method comprises the following steps that: a rock mass image is acquired; super-pixel segmentation is performed on the rock mass image; the super-pixel blocks are combined to obtain a rock mass joint fissure distribution map; the rock mass joint fissure distribution map is divided at equal intervals to form a plurality of divided areas, the joint rate and the joint number in each divided area are acquired, and the joint rate and the joint number are recorded as a group of data; the data recorded in each divided area is fitted with a formula Jv = a * Fvn + b to obtain a coefficient a, an index n and a constant b, wherein Jv is the joint number, and Fv is the joint rate; the maximum joint rate in each divided area is selected and substituted into the formula Jv = a * Fvn + b, and a corresponding joint number Jv is obtained; and a rock mass integrity coefficient Kv corresponding to the joint number Jv is obtained. The rock mass integrity coefficient can more accurately reflect the conditions of rock mass structure types, rock mass integrity and the like.

Description

technical field

[0001] The invention relates to the technical field of engineering exploration, in particular to a calculation method, device and storage medium for a rock mass integrity coefficient. Background technique

[0002] Integrity factor of rock mass K v , which can not only reflect the structure type and rock mass integrity, but also reflect the development degree and shape of structural planes. According to the GBT50218-2014 engineering rock mass classification standard, there is a corresponding relationship between the number of rock mass volume joints and the rock mass integrity coefficient. Therefore, the volume joint number of rock mass is an important parameter affecting the integrity coefficient of rock mass.

[0003] In the prior art, there are mainly three methods for measuring the volume joint number of rock mass: direct measurement method, distance method and strip number method. The direct measurement method requires the surface to be measured to ha...
