摘　　要：针对海港重力式码头胸墙及面层混凝土普遍存在裂缝的现况,我国现有的相关研究主要集中在材料、工艺等方面,对结构设计因素的影响研究不多。文中以具体海港重力式码头工程为依托,进行了裂缝状态及原因的分析,并从结构设计源头对码头胸墙和面层混凝土裂缝控制进行了优化,并得到了验证,取得很好的效果。Cracks in quay wall and concrete cover of gravity quay are quite common in harbor structures. Previous studies of crack formation are mainly focused on materials and processes. Little research is found in respect to structural design. In this paper, based on crack states and formation analysis of specific gravity quay, crack control of quay wall and concrete cover is optimized right from the beginning of structural design. This method has been verified and achieved good results. It may provide some advice for similar projects.
