“…The application of remote sensing methods for discontinuity mapping has increased significantly in the last decade. There are several applications of remote sensing techniques in rock engineering practice, such as rock mass characterization (Tonon and Kottenstette, 2006); (Ferrero et al, 2009); (Lato et al, 2009), (Lato et al, 2010); (Gigli and Casagli, 2011); (Lato et al, 2013); (Otoo et al, 2013); (Deliormanli et al, 2014); (Lai et al, 2014), rock slope stability (Strouth et al, 2006); (Ghirotti and Genevois, 2007); (Sturzenegger and Stead, 2009); (Lato and Vöge, 2011); (Lato et al, 2012); (Lato et al, 2015); (Tuckey and Stead, 2016) and underground excavations (Fekete et al, 2010); (Styles et al, 2010); (Fekete and Diederichs, 2013); (Lato and Diederichs, 2014); (Preston et al, 2014); (Walton et al, 2014); (Cacciari and Futai, 2017); (Delaloye et al, 2015); (Villalobos et al, 2017).…”

Geotechnical analysis of tunnels in complex geo-structural environments requires an advanced understanding of the inter-block structure effect on rock mass behavior, such as joints and fractures systems, bedding and foliation planes, among other discontinuity types. The conventional approach for preliminary geotechnical analysis of tunnels is based on a continuous-equivalent system representation of rock mass, i.e. without explicit consideration of systematic discontinuity systems. However, to obtain a closer to reality results of the rock mass expected behavior, geo-structural data should be included from the initial stage of geotechnical analysis. A case study is used to analyze the implications of the discontinuity systems inclusion on the rock mass stability around tunnel. Two-dimensional finite element numerical models were developed using three different models to the generation of rock discontinuity systems. The obtained results show that fracture intensity parameter help to generated more realistic two-dimensional DFNs.

“…The control software of data acquisition is mainly through the serial port to send data to the computer to provide data for 3D modeling of follow-up [22][23]. On one hand, the software needs to have the basic function of the software control system of numerical control, such as servo drive unit position control, I/O control and PLC control (limit switch, reset switch operation panel, etc.).…”

“…Traditional surveys are conducted via a window method or a line-scanning method (Gigli and Casagli, 2010;Kong et al, 2020), and require physical contact with the rock surface (Gigli and Casagli, 2010;Umili et al, 2013); however, this is time-consuming Kong et al, 2020) and subject to the expertise of the operator (Kong et al, 2020). With the advancement of measurement techniques, new non-contact surveying methods have been developed to acquire three-dimensional (3D) rock mass data, and include the total station method (Feng et al, 2001), close-range photogrammetry (De et al, 2012;Kaufmann, 2012;Francioni et al, 2019), and 3D laser scanning (Deliormanli et al, 2014;Monsalve et al, 2019;Wichmann et al, 2019;Jiang et al, 2020). These techniques have been rapidly utilized in slope monitoring (Kromer et al, 2019;Giacomini et al, 2020), rock mechanics and stability analysis (Firpo et al, 2011;Assali et al, 2014), and geomorphology (Brodie et al, 2015;Boothroyd et al, 2016), as well as the geological and geotechnical research fields (Giordan et al, 2018).…”

The geometric properties of rock mass discontinuities are essential for the evaluation of the safety of rock masses. Numerous studies have recently been performed on the extraction of discontinuity information. However, most methods are characterized by poor data collection and processing efficiency. This paper presents a UAV-based methodology for the accurate and complete acquisition of rock surface data, as well as the automatic extraction of discontinuity information. Moreover, a program called Random Sample Consensus (RANSAC) Discontinuity Detection (RDD) is developed to extract discontinuity information based on the proposed method. The conclusions of this research are as follows. 1) RANSAC Discontinuity Detection (RDD) can identify the feature point set of discontinuities from a raw point cloud, and can calculate the discontinuity orientation. 2) The boundary of a discontinuity can be precisely depicted using the improved Graham scan algorithm. 3) The orientations of marked discontinuities extracted by RDD are compared with those extracted by the three-point method in CloudCompare. The differences in the orientations extracted by the two methods are found to be less than 3° for flat discontinuities and only about 4.87° for rough discontinuities, which are within a reasonable error range in practical engineering applications. Therefore, the feasibility of the proposed method is verified.
