Pullout Resistance of Buried Pipeline in Cohesionless Soil Nearby Sloping Ground
(ASCE, 2020)The vertical and lateral pullout capacity of a long pipeline buried in a cohesionless soil nearby sloping ground has been investigated by using lower-bound limit analysis in combination with finite elements and linear ... -
Application of Soft Computing Techniques for Particle Froude Number Estimation in Sewer Pipes
(ASCE, 2020)Sedimentation in sewer networks is a major problem in urban hydrology. In comparison to the well-known classic sediment transport models, this study investigates the capabilities of soft computing methods, including multigene ... -
Influence of Grout Strength and Residual Deformation on Performance of Rehabilitated RC Pipes
(ASCE, 2020)Inserting a corrugated steel pipe (CSP) into an existing reinforced concrete pipe (RCP) is a common culvert rehabilitation technique in China. However, few studies have focused on the influence of grout strength and residual ... -
Optimal Pipe Sizing and Operation of Multistage Centrifugal Pumps for Water Supply
(ASCE, 2020)The operation of multistage pumps transporting water from the source to the delivery point requires balancing of the pressure at the junction of the pump and pipeline according to their characteristics. In this paper, ... -
Assessment of Failure Modes Caused by Water Hammer and Investigation of Convenient Control Measures
(ASCE, 2020)Economic and efficient transient control measures are always required to ensure safe and performant operation of water distribution networks (WDNs). This study presents extensive numerical investigations of some cost-effective ... -
Numerical Modeling of the Annular Failure Pressure during HDD in Noncohesive Soils
(ASCE, 2020)One of the critical issues that engineers, contractors, and owners encounter during horizontal directional drilling (HDD) is inadvertent return of drilling fluid (frac-out or hydraulic fracture) to the ground surface when ... -
Simulation of Crack Propagation in API 5L X52 Pressurized Pipes Using XFEM-Based Cohesive Segment Approach
(ASCE, 2020)The cohesive zone model (CZM) is one of the most widely used damage models to describe the fracture processes of brittle and ductile materials, and has been usually combined with the conventional finite-element method ... -
Reliability Assessment Model for Water Distribution Networks
(ASCE, 2020)The aging water distribution networks in the US are approaching the end of their useful life, and more than 240,000 pipeline breaks are estimated to occur every year, which corresponds to an average of 25 breaks (or ... -
Underground Sewer Networks Renewal Complexity Assessment and Trenchless Technology: A Bayesian Belief Network and GIS Framework
(ASCE, 2020)Significant investment is required to upgrade deteriorating underground sewer networks. Sewer failure and the subsequent rehabilitation process can have economic, social, and environmental impacts. It can disrupt critical ... -
Prediction of Critical Velocity in Pipeline Flow of Slurries Using TLBO Algorithm: A Comprehensive Study
(ASCE, 2020)Proper estimation of the critical flow velocity of slurries (Vc) is one of the most important parameters to design slurry transport in pipeline systems. In this study, three standard soft computing data-driven models ... -
Determining the Depth and Location of Buried Pipeline by Magnetometer Survey
(ASCE, 2020)This paper proposes a new approach to determine the depth and location of buried pipelines using the remote magnetic field measured by aboveground magnetometer surveys. Calculation is presented and verified by the experimental ... -
Optimal Location and Sizing of Scour Valves in Water Distribution Networks
(ASCE, 2020)Scour valves in a water distribution network are used to remove sediments that get deposited in the pipe and also to drain off water whenever it gets contaminated. The main governing factor associated with the design of a ... -
Influence of Soil Backfill on Vibration-Based Pipeline Leakage Detection
(ASCE, 2020)An estimated 20% of treated fresh water is lost through leakage in distribution pipeline infrastructure in the United States. As a result, significant research has been devoted to developing technologies that will assist ... -
