Stability assessments of caverns in jointed rock comparing Block Theory and 3DEC [PDF]
, 2008 Diskontinuitäten in Form von Klüften, Störungen und Scherzonen haben einen großen Einfluss auf die Standsicherheit von Bauwerken im Festgestein. Dies trifft besonders auf große Hohlraumbauwerke wie Kavernen zu, denn das Trennflächengefüge beeinflusst den

Evaluation of scale and loading direction effects on strength and deformability of jointed rock mass: case study of Tazareh coal mine, Iran [PDF]
International Journal of Mining and Geo-Engineering, 2022 Determining strength and deformation of jointed rock masses is an inevitable part of geomechanical projects. Strength and deformability of a rock mass with stochastic joint sets is conceivably anisotropic and is mainly controlled by joints mechanical and

Hazard zoning and assessment of rockfalls based on AHP-3DEC
Zhongguo dizhi zaihai yu fangzhi xuebao, 2023 Restricted by the surface smoothness and topography, it is impossible for some high-speed railways on mountainous regions to avoid parts of rockfall development sections, posing great safety challenges to construction projects and railway operations.

Die Modellierung großer Felsgleitungen mittels 3DEC [PDF]
, 2016 Im Steinbruch bei Spitz an der Donau kam es in der Vergangenheit immer wieder zu Felsstürzen unterschiedlicher Größenordnungen. Beim letzten großen Ereignis glitt im Jahr 2002 ein Felsvolumen zwischen 60.000 und 85.000 m3 ab. Abschätzungen haben ergeben,

Journal of Rock Mechanics and Geotechnical Engineering, 2014 A grain-based distinct element model featuring three-dimensional (3D) Voronoi tessellations (random poly-crystals) is proposed for simulation of crack damage development in brittle rocks. The grain boundaries in poly-crystal structure produced by Voronoi

Flowchart of DEM Modeling Stability Analysis of Large Underground Powerhouse Caverns
Advances in Civil Engineering, 2020 The power of the Distinct Element Method (DEM) in solving the stability of underground powerhouse caverns (UPC) is discovered, but when does the DEM need to be adopted? What problems can be solved?
