Challenging Issues in Modeling Deterioration of Combined Sewers
Publisher: American Society of Civil Engineers
Abstract: The understanding of sewer deterioration mechanisms helps asset managers in developing deterioration models to estimate whether sewers have deteriorated sufficiently for likely collapses. While an accurate deterioration ...
Rehabilitation Alternatives for Concrete and Brick Sewers
Publisher: American Society of Civil Engineers
Abstract: Sanitary and storm sewer collection systems are aging, and the reactive approach traditionally used for repair and rehabilitation is no longer appropriate. A comprehensive program including assessment of the existing ...
Near Real-Time HDD Pullback Force Prediction Model Based on Improved Radial Basis Function Neural Networks
Publisher: ASCE
Abstract: Pipeline pullback is a crucial part of horizontal directional drilling (HDD) construction. Accurate pullback force prediction is the prerequisite for ensuring construction safety. However, owing to the influence of factors ...
Novel Data-Driven Framework for Predicting Residual Strength of Corroded Pipelines
Publisher: ASCE
Abstract: For the residual strength prediction of corroded pipelines, the existing standard has a small application range, and the finite-element method has too many assumptions. This paper proposes a new data-driven prediction ...
Prediction of Construction Traction Force for Corroded Pipeline Rehabilitation Using Multilayer Composite Liners
Publisher: American Society of Civil Engineers
Abstract: The rehabilitation of corroded pipelines is critical for maintaining the global energy supply chain. Traditional repair methods, involving the replacement of damaged sections, are economically prohibitive and environmentally ...
Comparison of Technologies for Condition Assessment of Small-Diameter Ductile Iron Water Pipes
Publisher: ASCE
Abstract: Among the various diameter classes of ductile iron pipe (DIP) used in water distribution systems, small-diameter pipes [i.e., pipes with a diameter less than or equal to 305 mm (12 in.)] represent the largest ...
A Feature Selection–Based Intelligent Framework for Predicting Maximum Depth of Corroded Pipeline Defects
Publisher: ASCE
Abstract: Corrosion is one of the most common defects of buried pipelines. Accurate prediction of the maximum pitting depth of corroded pipelines is conducive to assessing the remaining strength of the pipeline. In the context of ...
Leveraging Machine Learning for Pipeline Condition Assessment
Publisher: ASCE
Abstract: Pipeline condition assessment is a cost-effective method to determine the status of pipeline structure and predict failure probability. Although 100% inspection may not be feasible for decision makers, recent advancements ...
Empirical Assessment of Unobserved Heterogeneity and Polyvinyl Chloride Pipe Failures in Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: An understanding of the failure patterns of pipes in water distribution systems is critical to cost-effective system-maintenance planning. Failure patterns, which typically measure the frequency of water main breaks in a ...
