摘　　要：用海政策调整后,传统满堂式沉箱结构+后方回(吹)填方案在获得用海许可存在困难。结合工程实例,通过理论计算和物理模型试验对比,在结构受力、构造及施工方面进行优化,提出沉箱墩+叠合板结构方案,具有岩面浅、波浪高且使用荷载大的特点。该方案在日照港岚山港区得到成功应用,码头运营状况良好,取得良好经济效益,可为类似条件下码头的设计和建设提供借鉴。After adjustment of the sea use policy,the traditional contiguous scheme with caisson structure+rear backfilling dredger filling makes it difficult to obtain approval for sea use.Combined with engineering examples,through the comparison of theoretical calculation and physical model test,this paper optimizes the structure force,structure,and construction and proposes the caisson pier+composite slab structure scheme,which has the characteristics of shallow bedrock surface,high wave,and large load.The scheme has been successfully applied in Lanshan Port Area of Rizhao Port.The operation of the wharf is in good condition,and good economic benefits have been achieved,which provides a reference for the design and construction of the wharf under similar conditions.
