报告简介:

Analysis of geotechnical engineering are inherently complex due to the heterogeneity of the stratigraphy and the influence of pore fluid pressure. Consideration of such types of complexities requires application of advanced numerical techniques. Many numerical techniques have been developed in the literature to address geotechnical engineering analysis. Nevertheless, mesh generation, especially when considering the heterogeneity of strata and the complexity of the geometry is still a challenging problem when conventional numerical techniques are applied. The scaled boundary finite element method is semi-analytical numerical technique that was introduced in the late 1990’s. The formulation is sufficiently flexible such that it can be formulated on polygons with arbitrary number of sides (in 2D) or facets (in 3D). This advantage can be exploited for image-based mesh generation of complex geometries with inherent heterogeneities, which are ubiquitous in geotechnical engineering applications. This presentation will focus on application of the Scaled Boundary Finite Element Method in geotechnical engineering problems focusing specifically on the stability of open cut mines and the optimisation of the mine geometry. The advantages of the Scaled Boundary Finite Element Method in image-based mesh generation and efficient computations using quadtrees will be exemplified.
