Mechanical Response and Soil Arching Mechanism of Buried Pipelines in Landslide Zones

Mechanics of Buried Pipelines Loading under Localized Subsidence: A Three-Dimensional Soil-Arching Approach

The combined effects of localized subsidence-induced size effects and pipe–soil interaction render conventional load calculation theories inadequate for accurately evaluating pipeline loads after foundation subsidence. To overcome this limitation, the 3D transfer characteristics of vertical loads acting on buried pip...

Numerical Investigation of the Formation Mechanism and Mitigation of a Clayey Landslide Under Excavation–Rainfall Coupling

An excavation-induced clayey landslide in Jianshui County, Yunnan Province, China, threatens a national refined oil pipeline near the rear slope. Field investigation, borehole logging, laboratory testing, and three-dimensional finite-element analyses were integrated to investigate the excavation–rainstorm instability m...

Mitigation of Dynamic Load-Induced Pipeline Displacements Using EPS Geofoam

Seismic Response and Failure Mechanisms of Tunnels Constructed Using the Pipe Roof Preconstruction Method

Iterative Approach for Analyzing Jointed Pipeline Response Considering Pipeline‐Soil Gap Induced by Down‐Crossing Tunnel

In underground space engineering, the down‐crossing of a tunnel beneath an existing pipeline often leads to soil settlement beneath the pipeline, creating a gap between the pipeline and the soil. This can result in the loss of local support under the pipeline, significantly decreasing its safety and reliability. To a...

Soil–Structure Interaction and Arching Effect for Buried Flexible Pipelines in an Induced Trench: Experimental and Numerical Investigation

Flexible culverts have been widely used in underground engineering, but the deformation control of buried flexible pipelines during trench backfilling remains challenging. In this study, foamed concrete was introduced as a lightweight backfill material below the pipe springline, with a maximum relative height of 0....
