Use of Digital Terrestrial Photogrammetry in rocky slope stability analysis by Distinct Elements Numerical Methods

摘要

Current approaches to rocky slope stability analysis require knowledge of the geometrical-structural setting, as well as the physical-mechanical properties of the intact material and its discontinuities. The physical-mechanical properties are derived from in situ and laboratory tests, whereas the geometrical characteristics come from field attitude measurements. Frequently, the inaccessibility of walls does not allow direct measurement of discontinuity surfaces by traditional geological methods. In such cases, data can only be obtained by statistical memods. Although this approach is significant and provides spatial meaning, it is ineffective for deterministic analysis.
