Abstract
The Wangting Water Conservancy Hub is a crossing structure where the Wangyu River intersects the Beijing-Hangzhou Grand Canal.As a key hydraulic project on the Wangyu River,it plays an important role in flood control,waterlogging drainage,water diversion,and navigation in the Taihu Lake basin.Under extreme weather conditions,strong human disturbances,tidal river network effects,and significant temporal variability,the operational and hydrological conditions of the Wangting Hub have undergone major changes,making it urgent to reassess the ultimate indicators for its control and operation.Taking structural safety as the baseline,this study adopts literature review,standardized calculation,full-envelope coverage,and index correlation assessment methods to systematically analyze three core indicators(controlled water level,sluice discharge,and water level difference)and five key influencing factors(structural stability,seepage safety,hydraulic conditions,gate hoisting force,and gate structural strength and stiffness).A comprehensive assessment is then conducted to determine reasonable ultimate values of the hub under the coupling and constraints of multiple factors.The findings provide a scientific basis for the control and operation of the Wangting Water Conservancy Hub and also offer reference and demonstration significance for studying ultimate indicators of sluice control and operation in different types of sluices,such as open-type and breastwall-type structures.关键词
