Experimental Study on Sluice Layout Optimization in the Beixi Flood Diversion Sluice-Gate Reconstruction
摘要
Abstract
The Beixi Flood Diversion Sluice-Gate has been rated as a"Class IV sluice"requiring reconstruction due to seepage failure and structural aging caused by long-term high-water-level operation.This study conducted hydraulic model experiments to analyze issues in the design scheme,including disturbed flow patterns through the sluice and excessive flow velocity at the downstream left bank.Improvement measures such as guide wall heightening,shoreline and beach adjustment,and optimization of energy dissipation pools were proposed.Experimental results demonstrated that the optimized scheme significantly enhanced flow patterns through the sluice,increased discharge capacity,centralized downstream flow distribution,reduced near-bank flow velocity,and improved anti-scouring safety of downstream slopes.The research outcomes provide theoretical and technical references for similar engineering projects.关键词
