Uncertainties, Risk, and Reliability Aspects of Underground Blast Modeling Around Buried Pipeline in Geotechnical Engineering Context
摘要
Modeling is only part of decision-making. The most common limitation of modeling in practice is not explicitly considering risk, uncertainties, and reliability. Underground blasting near vital global pipeline systems is the focus of this study. Disruptions in these systems could affect local businesses, economies, and living conditions. Geotechnical engineering must evaluate underground blast modeling due to explosion unpredictability, soil instability, and seismic risk assessment for utility pipelines. In risk management for buried pipeline systems, uncertainty, especially epistemic uncertainty, is crucial. Incomplete knowledge of system behaviors and environmental conditions causes epistemic uncertainty, which is essential to risk assessment and management. This research uses a numerical model (developed in Abaqus/Explicit) to analyze these uncertainties, which improves the study's conclusions. This paper also contextualizes several application areas related to engineered systems’ design and construction stages using the Burland Triangle framework, which incorporates uncertainty into geotechnical engineering practices. The research evaluation and study findings analyze geotechnical reliability and epistemic uncertainty. This analysis shows how these factors aid pipeline design, construction, operation, maintenance, and retrofitting decision-making. The study's recommendations aim to help geotechnical engineer-required regulatory bodies assess risks more logically.
