摘要
碧湾拦河闸改建橡胶坝工程运行中发现坝体裂缝、混凝土老化、下游冲坑等较大安全隐患,须进行除险加固。经技术经济适用性综合比较,选用翻板钢坝加固方案。该方案不束窄过流断面,操作简便,启闭灵活,不阻碍行洪,并可形成较好的景观效果。本文详述了该设计方案,并对溢流坝段泄流能力和坝基抗滑稳定进行了计算,可为类似钢坝设计提供参考。
Major safety hidden dangers appear in Biwan River sluice reconstruction rubber dam engineering operation, such as dam cracks, concrete aging, downstream pit flushing, etc., and it should undergo risk removal and reinforeement. The reinforcement plan of tiled steel dam is selected through the comprehensive comparison of technical and economic applieability . The plan does not restrain narrow flow cross section with simple operation and flexible closing-opening. Flood flow is not hindered. Better landscape effect can be formed. The design plan is described in the paper, and the discharge capacity of the overflow dam section and the anti-sliding stability of the dam foundation are calculated, which can provide reference for similar steel dam design.
