Bearing Capacity of Large-diameter Metro Shield Tunnel in Soft Soil Layer
Published 2025-07-01“…The bearing process of large-diameter shield tunnel can be divided into four stages: elastic stress stage (the convergence deformation δ reaches 0 to <2.0‰D, D as the tunnel outer diameter), slight damage stage (δ reaches 2.0‰D to <5.6‰D), rapid damage development stage (δ reaches 5.6‰D to 9.4‰D), and near failure stage (δ reaches 9.4‰D or more). Among them, the structure bearing state in elastic stage is good, the structure durability in slight damage stage is reduced, but the bearing safety is still good. …”

POD Analysis of Flow Field Characteristics of Jet Oscillators with Different Length-to-Diameter Ratios
Published 2025-07-01“…Additionally, the obtained flow field was subjected to proper orthogonal decomposition (POD) to extract the first four POD modes of the flow field along with the corresponding time coefficient evolution curves. Research indicates that the periodic evolution of the main vortex structures inside and outside the flow field of the jet oscillator with different length-to-diameter is similar, while the performance of feedback vortices differs from that of small-scale vortex bubbles. …”

The interplay of trophic interactions and game dynamics gives rise to life-history trade-offs, consistent personalities, and predator–prey and aggression power laws
Published 2025-01-01“…Here, we introduce an eco-evolutionary model of trophic interactions between predators and prey and show that the flow of resources in the ecosystem results in the scale-invariant spatial and temporal structure of ecosystems. In contrast to conventional approaches that rely on fitness-based selection, evolution in our eco-evolutionary framework is a direct consequence of ecological interactions. …”
