Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Grouting diffusion range is the key to evaluate the grouting effect. In this study, a theoretical model of noncohesive sediment erosion damage was established, and the main parameters affecting erosion were qualitatively analyzed. Secondly, based on the computational fluid dynamics (CFD)–discrete element method (DEM) coupling method, the effect of ...

Effects of Multistage Geotechnical Erosion on Dynamic Mechanical Response of Buried Pipelines
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.River‐spanning pipelines are prone to serious hazards during flooding events, which can trigger erosion, exposure, and large‐scale flotation. In this research, a numerical simulation framework was developed using smoothed particle hydrodynamics (SPH) to analyze the dynamic behavior of pipelines subjected to dam‐breach flood scenarios.
