Effects of Spray-On Lining Rehabilitation on Behavior of Buried Corroded Metal Pipes Subjected to Surface Loading
(ASCE, 2024/02/01)Corrugated metal pipes (CMPs) buried in the ground for decades may get corroded and lose their structural capacities supporting surface loading, leading to the end of their service life. Three maintenance options are ... -
Physical Model Test Investigation of Mechanical Properties of Double Pipe Culverts Subjected to Vertical Loading
(ASCE, 2024/02/01)The performance of double-pipe culverts remains unclear due to insufficient research on double culverts. This study made use of polyvinyl chloride pipe to simulate culverts. The effect of culvert spacing and fill height ... -
Maximum Likelihood Estimation to Localize Leaks in Water Distribution Networks
(ASCE, 2023/11/01)Leaks cause significant water loss in underground water distribution networks, which makes it critical that utilities quickly detect, localize, and repair them. Acoustic leak detection and localization methods using ... -
A New Strategy for Mitigating Pipeline Uplift in Liquefied Soils
(ASCE, 2023/11/01)Seismic-induced liquefaction is one of the main hazards for pipelines buried in saturated granular materials. When soil is partially or completely fluidized, a lifeline, although installed in superficial trenches in which ... -
A Novel Low-Pressure Release Method Based on Inlet Regulation for Users with Low Demand Scenario
(ASCE, 2023/11/01)Due to the mismatch between gas production and consumption in the gas delivery system (GDS), reduced customer demand can easily lead to overpressure and gas release. Companies mainly use high-pressure release (HPR) to lower ... -
