Research on the Risk Assessment of the Seismic Subsidence of Underground Water Transmission Pipeline in Loess Area
Publication: ICCREM 2023
ABSTRACT
The seismic subsidence risk assessment of underground water transmission pipeline in loess area is important to judge its seismic subsidence risk level, reduce geological disasters caused by seismic subsidence, and improve the safety of water transmission projects. To make the risk evaluation more scientific, a risk evaluation index system is established from three aspects: loess factors, seismic factors, and water transmission pipeline factors, and the weight calculation method of subjective and objective combination assignment is adopted, and the improved gray clustering model is selected for comprehensive evaluation. The model was applied to the loess plateau section of the second phase of Shaanxi Province Hanjiang-to-Weihe River project, and the evaluation results indicate that its risk is low, and corresponding risk control measures are proposed. The research results have certain value for the safety analysis of underground water transmission pipeline projects and the risk assessment of loess seismic subsidence of similar projects.
