Abstract EN
A structural domain represents a volume of a rock mass with similar mechanical and hydrological properties.
To demarcate structural domains (or statistically homogeneous regions) in fractured rock masses, this study proposes a three-parameter simultaneous analysis method (3PSAM) that simultaneously considers rock fracture orientation, trace length, and aperture to evaluate statistical homogeneity between two regions.
First, a 102-patch three-dimensional Schmidt net, which represents a new comprehensive classification system, is established to characterize rock fractures based on their orientation and aperture.
Two populations of rock fractures can then be projected to the corresponding patches.
Second, the Wald–Wolfowitz runs test is used to measure the similarity between the two populations by considering the fracture trace lengths.
The results obtained by applying the 3PSAM to seven simulated fracture populations show that the homogeneity is influenced by both the distributions of the fracture parameters and the sequences of the fracture parameters.
The influence of a specific combination sequence makes it impractical to analyze the rock fracture parameters individually.
Combined with previous methods, the 3PSAM provides reasonable and accurate results when it is applied to a fractured rock slope engineering case study in Dalian, China.
The results show that each fracture population should be identified as an independent structural domain when using the 3PSAM.
Only the 3PSAM identifies the west exploratory trench 2 and the east exploratory trench as being nonhomogeneous because the difference in the aperture of the two fracture populations is considered.
The benefit of the 3PSAM is that it simultaneously considers three parameters in the demarcation of structural domains.
