  The evaluation of advanced soil models for the cyclic soil-structure interaction (SSI) of integral bridges is crucial for improving the accuracy of structural performance assessments under repeated loading conditions. Integral bridges, which lack expansion joints, rely heavily on the interaction between the superstructure and the surrounding soil to absorb and redistribute stresses. During thermal expansion and contraction cycles, this interaction becomes highly nonlinear, making traditional modeling approaches inadequate. Advanced soil constitutive models—accounting for strain hardening, hysteresis, and soil degradation—offer a more realistic representation of cyclic behavior. By integrating these models into finite element analyses, researchers can predict bridge response more accurately, optimize design, and enhance long-term durability. This research supports resilient infrastructure by reducing maintenance costs and mitigating structural vulnerabilities related to soil behav...

  Microplastics, emerging as pervasive environmental pollutants, have raised serious concerns regarding their impact on terrestrial ecosystems. In the case of mulberry seedlings, exposure to microplastics has been shown to significantly affect plant growth and the surrounding soil microecology. These synthetic particles can interfere with root development, nutrient uptake, and biomass accumulation. Moreover, microplastics alter the soil’s physical and chemical properties, disrupting the balance and diversity of soil microbial communities that are essential for plant health. The findings highlight the urgent need for deeper investigation into microplastic pollution in agricultural environments, especially given the economic and ecological importance of mulberry cultivation.

       The seismic internal stability analysis of reinforced soil walls under wave loading is a critical aspect of geotechnical and coastal engineering. These structures, widely used in infrastructure development, are subjected to dynamic forces not only from earthquakes but also from wave-induced loading in coastal or riverine environments. The interaction between seismic waves and hydrodynamic forces significantly influences the stress distribution and strain behavior within the reinforced soil mass. Advanced numerical simulations and analytical methods are employed to evaluate the internal stability, focusing on factors such as reinforcement tensile forces, soil-reinforcement interaction, and potential failure surfaces. Understanding these complex interactions is essential for designing resilient retaining structures that can withstand both seismic and hydraulic disturbances, ensuring long-term safety and performance.

  The evolution of thermal conductivity in sand-clay composites under one-dimensional compression is a critical subject in geotechnical and environmental engineering. As pressure increases, the rearrangement of soil particles, reduction in porosity, and redistribution of moisture content significantly influence the heat transfer capabilities of the composite. Initially, thermal conductivity tends to increase with compression due to improved particle contact and reduced air voids, which are poor conductors of heat. However, the rate of increase may vary depending on factors such as clay content, water saturation level, and grain size distribution. Understanding these variations is essential for designing effective underground thermal energy storage systems, evaluating soil behavior under load, and predicting heat transfer in layered soils in various engineering applications.
