毕 业 论 文（设计） 题目：青岛港董家口港区防波堤设计 学院专 业班 级学 号学生姓名指导教师Abstract: The port of Dongjiakou is an important transit base for bulk cargo transportation,the port is located in the open sea. wave, tide, wind and so on influent the berthing of ships conditions. So it is necessary to build the breakwater, impact against the above environment on the normal operation of the port. The construction of the breakwater, need to take into account the influence of natural conditions and water depth in front of the dike, the reasonable layout of the breakwater. In addition, the analysis of port sediment analysis and engineering geology, make it more effective and stable operation in the future. The plane layout of breakwater, we considered the highest and lowest tidal level, through the design specification of breakwater construction, calculation of crest width and height, determine the cross section of the. In order to reduce the impact of wave force on the breakwater, layout 6T Accropode energy dissipation. Finally, the stability calculation of parapet foundation stability and settlement. Dongjiakou breakwater is located in the sea waters, in order to protect the stability of the port, from the weather sloping breakwater. Is an important part of coastal ports. Keywords: breakwater; wave overtopping; crest wall; general layout 目录 第1章 概述 1 第2章 设计条件 2 2.1地理位置及交通 2 2.2气象 2 2.2.1 气温 2 2.2.2 降水 2 2.2.3 雾况 2 2.2.4 风况 2 2.3 工程水文 3 2.3.1 潮位特征值 3 2.3.2 设计水位 4 2.3.3 乘潮水位 4 2.3.4 波浪 4 2.3.5 潮流 5 2.4地质 6 2.5 地形地貌及泥沙运动 7 2.6 地震 7 2.7结构安全等级 7 第3章 断面尺寸的确定 8 3.1 胸墙顶高程 8 3.2堤顶宽度 9 3.3护面块体稳定重量和护面层厚度 9 3.3.1护面块体稳定重量 9 3.3.2护面层厚度 10 3.3.3 垫石层的重量与厚度 10 3.3.4堤前护底块石稳定重量和厚度 11 第4章 胸墙设计及稳定性的计算 12 4.1 胸墙的设计 12 4.2断面胸墙抗滑稳定性验算 19 4.3 断面胸墙抗倾稳定性验算 20 第5章 地基稳定性验算 21 第6章 地基沉降计算 23 第7章 总结 24 参考文献 25 概述 青岛港是山航运发展的枢纽，董家口港区在散货装卸运输等方面，是青岛港的重要功能补足。董家口港区的交通方便，国道和省道穿越了镇区；同三高速公路从镇区北面穿过，在镇驻地的西面设有进出口；青岛的滨海大道穿过镇区的东面，西面与204国道相连接，泊里东面距青岛前港湾45海里。 工程选址在琅琊台湾外海海域，旁边的鸭岛和董家口半岛对这边海域形成了
