Numerical Study of Transient Flow Characteristics in Pipelines during Pigging Operations Using the Blasting–Purging Method
(American Society of Civil Engineers, 2025)AbstractThe blasting–purging method (BPM) is characterized by high efficiency, low technical demand, easy operation, and strong sand-carrying capacity. BPM has been widely used in oil–gas–water pipelines. However, it is ... -
Analysis of Consolidation and Undrained Shearing of Saturated Clays Subjected to Thermal Loading
(American Society of Civil Engineers, 2026)Abstract This paper investigates the mechanical response of saturated fine-grained soils subjected to thermal loading under different states of stress. A thermoplastic soil constitutive model that incorporates stress-induced ... -
Research on the Calculation Method of Crack Driving Force of Nitrogen-Containing Supercritical Carbon Dioxide Pipelines
(American Society of Civil Engineers, 2025)AbstractThe released supercritical carbon dioxide does not decrease the pressure at the crack top of the pipeline due to phase transition. When mixed with nitrogen, the maintained pressure at the crack top, related to the ... -
Significance of Creep Behavior of the Pipe Wall on Optimal Sizing of an Air Chamber in Long-Distance Viscoelastic Pipes
(American Society of Civil Engineers, 2026)AbstractViscoelastic pipes have lower wave speeds than typical rigid materials, but they also display a lag in their strain response when subject to the stresses associated with transient loadings. Although many transient ... -
Double-Layer Data-Driven Risk Assessment and Prediction of Drainage Pipeline Networks
(American Society of Civil Engineers, 2026)AbstractSewage pipeline network accidents occur frequently, posing a serious threat to the life and property safety of residents. There is an urgent need for methods that can effectively identify the key factors of pipeline ... -
Model Test Investigation of Eccentric Load Effect on a Gully Installed Circular Culvert
(American Society of Civil Engineers, 2025)AbstractSome mountainous areas have a relative height difference of up to 2 km and an average slope of more than 13°, and most high-fill culverts are laid asymmetrically, resulting in uneven distribution of earth ... -
Impact of Fracture Density of Stimulated Reservoir Volume on Casing Deformation in Horizontal Shale Gas Well
(American Society of Civil Engineers, 2025)AbstractCasing deformation in horizontal shale gas wells is a critical issue during multistage hydraulic fracturing. This study investigates the impact of fracture density and its nonuniformity on casing deformation using ... -
Locating Water Supply Pipeline Leaks Using Multivariate Variational Mode Decomposition and Multichannel Singular Spectrum Analysis
(American Society of Civil Engineers, 2025)AbstractEnvironmental noise interference makes it difficult to extract leakage features from vibration signals during pipeline leaks, resulting in inaccurate leak localization. In order to reduce noise in the signal, improve ... -
Optimization of Surface Systems in Mature Oilfields with High Water Content
