This study presents a dynamic inversion method for the concrete gravity dam on soft rock foundation, aiming to accurately characterize time-dependent trend of dam’s mechanical properties. Conventional static methods often overlook temporal variations in material behavior, particularly long-term weakening foundations under environmental influences. To address this limitation, an improved particle swarm optimization (PSO) algorithm is developed parameter inversion, combining real-time...
Soil–rock binary structure slopes are a unique and common phenomenon in water conservancy geotechnical engineering, with complex stability issues that challenge traditional evaluation methods. This paper proposes the Partitioned Rigid Element–Interface Element–Finite Element (PRE-IE-FE) method, novel numerical technique addresses computational efficiency accuracy slope analysis. The method integrates composite destabilization modes along soil interior, soil–rock contact surface, rock...
The stability analysis of rock slopes has been a prominent topic in the field mechanics, primarily due to widespread occurrence discontinuous structural planes masses. Based on this complex characteristic slopes, paper proposes novel numerical method, Partitioned-Rigid-Element and Interface-Element (PRE-IE) method. In PRE-IE structure is modeled as several rigid bodies planes, which are, respectively, divided into partitioned elements interface elements. Taking contact force node pairs...
Human factors are introduced into the dam risk analysis method to improve existing management theory. This study constructs path of human factor failure in collapse, explores pattern each node, and obtains performance shaping (PSFs) therein. The resulting model was combined with a Bayesian network, sensitivity performed using entropy reduction. obtained pathway consisting four components: monitoring awareness, state diagnosis, plan formulation operation execution. Additionally, PSFs set...
