20.500.12556/RUL-163631 System reliability analysis of concrete arch dams considering foundation rock wedges movement a discussion on the limit equilibrium method In this paper, a discussion on the applicability and limitations of the limit equilibrium method is presented. In this manner, the reliability of a concrete arch dam-foundation system under static loading is evaluated by considering a set of potentially moveable rock wedges in the foundation. The safety of the system is assessed utilizing a quasi-analytical method, which employs the limit equilibrium method and numerical analysis to calculate the sliding safety factors and the dam trust forces, respectively. The reliability is evaluated using the Latin Hypercube Sampling method. Random variables in the system are the friction angle, cohesion, and the Grout Curtain Efficiency Coefficient. In the end, the influence of two parametric variables of discontinuities, elastic slip and rock mass deformability modulus, on the rock wedges’ sliding safety factor is evaluated by comparing the results of the quasi-analytical method with the purely numerical method. The results show that in the case of complicated geotechnical conditions, the limit equilibrium method may not reflect real-world failure scenarios. double-curvature concrete arch dams reliability analysis foundation stability limit equilibrium method numerical models Latin Hypercube Sampling ločna pregrada betonska pregrada zanesljivostna analiza stabilnost temeljnih tal mejna stanja numerična analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-09 13:55:22 2024-10-09 13:55:28 2024-10-11 03:37:53 0000-00-00 00:00:00 2024 0 0 17 str. iss. 10, art. 176 Vol. 9 Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.62 2412-3811 10.3390/infrastructures9100176 210858499 Soltani,_Escuder,_Klun-System_reliability_analysis_of_concrete_arch_dams_considering_foundation_rock_wedges_movement....pdf Soltani,_Escuder,_Klun-System_reliability_analysis_of_concrete_arch_dams_considering_foundation_rock_wedges_movement....pdf 1 E43782DB328684CF4F2AB13BFF73E146 c35b372c3408547fb43a5647e2fbb4cad2cc9470581d4b93549efc7a32f97474 7bc51a92-8636-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193470 https://www.mdpi.com/2412-3811/9/10/176 1 34089953-8635-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193468 Fakulteta za gradbeništvo in geodezijo 0 0 0
