由于厦门城市规划和港口功能区划调整,需将厦门港东渡港区19#泊位的煤码头改建为5万吨级的多用途码头(按靠泊10万吨级集装箱船预留),拟建的码头结构型式为沉箱重力式。为此,需将旧的高桩梁板码头拆除。介绍高桩梁板码头拆除方案的设计及施工,重点分析岩质海岸地质条件下预制桩的拆除方案。

According to Xiamen municipal master plan and port functional zone＇s adjustment, the coal terminal of Xiamen Port Dongdu Port Area Berth 19^# is required to be reconstructed to a 50 000 dwt multi-purpose wharf （prepared for berthing 100 000 dwt container ships）, which adopts caisson-type gravity structure. So, the existed high-piled slab ＆ beam wharf shall be demolished. This paper describes the design and construction of the demolishing scheme of the high-piled wharf, and analyzes mainly the demolishing scheme of precast piles under rocky coast.
