| description | Background:The existing pipeline siltation analysis lacks the analysis of the influence of pipeline siltation intensity on the water level depth of the manhole.Objective:To address these issues, in this study, the high-resolution numerical simulation model of ‘silted pipeline-manhole' was established.Methods:First, a spatial and temporal hydraulic response model of the ‘silted pipeline-manhole' system is constructed. The vibrational differential equation of the ‘silted pipeline-manhole' system is then adopted to quantify the physical boundary constraints on the fluid–solid coupling relationship. The local and global feature search capabilities were enhanced by an embedded self-attention network, which in turn established an intelligent early warning model for manhole water levels in silted pipelines.Results:The results of the test analysis showed that, owing to the blocking effect of siltation, the water level of the manhole at the first end of the silted pipe was high, leading to a decrease in the water level of the manhole at the tail end. The pipe with a transverse siltation intensity of 10% showed an 8.07% reduction in the maximum overflow flow rate, whereas the pipe with a longitudinal siltation intensity of 5.2% exhibited a 15.09% reduction, suggesting that longitudinal siltation intensity has a more significant impact on pipeline failure.Conclusion:The research results provide technical support for the diagnosis of pipeline siltation and flood risk assessment considering the change of water level in the manhole and the inlet and outlet flow velocity of the pipe section. |
