深圳妈湾电厂码头结构设计

Terminal Structural Design for Shenzhen Mawan Power Plant

深圳妈湾电厂码头工程包括2个5万吨级专用卸煤泊位,其码头使用荷载大:距码头前沿线33m起堆煤高度15m。码头结构采用对荷载适应性强的沉箱重力式。为减少码头前沿的反射波高,巧妙地在卸荷板和胸墙中设置进、出水孔和消浪室。并且对基槽开挖深度进行优化设计,取得了显著的经济效益。

The terminal for Shenzhen Mawan Power Plant includes two50,000dwt specialized coal-unloading berths and its heaped load is rather heavy:the coal stacking height is up to15m from33m behind the quay line and concrete caisson is adopted for adapting the heavy loads.Water inlet&outlet and wave breaking chambers are arranged for relieving slab and breast wall to reduce the reflected wave height alongside the berth.Optimization for excavation depth of foundation trench is carried out and notable economic benefit is achieved.
