Geotechnical modelling and subsurface analysis of complex underground structures using PLAXIS 3D

Abstract In this study, analysis of complicated underground structure Horemheb tomb (KV57) at Luxor, Egypt by using the software PLAXIS 3D is adopted and deformation that occurs in body after applied failure load detected; loads are obtained from series laboratory tests. Then, modelled finite element code to perform accurate three-dimensional stability complex geotechnical engineering rock mechanics. These monumental structures have been analyzed method FEM obtain accrued into so beneath surface calculated effective stress, shear stress horizontal displacements. order modeling requires soil parameters laboratorial elastic–plastic Mohr–Coulomb model used as material model. It involves five namely, Young’s Modulus (E) poison’s ratio (ν) for elasticity, friction angle (φ) cohesion (c) plasticity. To set up boundary condition, standard fixities option used. As a result full fixity base free condition side geometry generated. Numerical Engineering valley kings west bank Luxor was carried out through following four main steps: (1) Evaluation surrounding rocks (marl limestone marl shale) experimental research Roclab program Hoek Brown Mohr- Coulomb fit classification criterion mass standards particular global strength coefficient. Also specify characteristics Esna Shale different methods such swelling test, potential, pressure, addition, discussion role expansive deterioration archaeological buildings sites. (2) Quantitative qualitative estimates relevant factors affecting tomb, especially overloading, fixed, geographic, dynamic. (3) Integrated cemetery environment displacement identification volumetric strains plastic points advanced symbols programs 3D. (4) The rapeutic retrofit policies techniques fixed monitoring control systems needed strengthen stabilize cemetery, where refers KV57 excavated it poor rocks. mechanical behavior simulated assuming foundational soften elastic flexible captures fragile mechanisms progressive substrate failure. pillar treatments ground support strategies discussed.
