青岛港董家口港区防波堤设计

摘要：青岛港董家口港区是散货运输等的重要中转基地，港区位于外海海域，波浪、潮流、风等都是影响港区内船舶泊稳的条件。所以需要修建防波堤，以抵御以上环境对港区正常运行的影响。防波堤的建造，需要考虑到自然条件和堤前水深的影响，合理的对防波堤进行布置。另外，对港区泥沙淤积分析和工程地质分析，使其在今后的运行更加有效和稳定。防波堤的平面布置，我们考虑到最高和最低潮位，通过防波堤施工设计规范，计算堤顶宽度和高度，确定横截面的情况。为了减少波浪力对防波堤冲击，布置人工护面块体消能。最后进行胸墙的稳定、地基稳定性和地基沉降的计算。董家口防波堤地处外海海域，是为了保护港区稳定，免受恶劣天气影响的斜坡式的防波堤。是沿海港口的重要组成部分。

Breakwater design in Dongjiakou district of Qingdao port

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
