摘要：青岛港历史悠久，地处中国山东胶州湾，港区内水域宽，水深大，能够四季通航，港湾整体呈现出口小腹大的特点，是非常理想的港口，为中国重点港口之一。青岛港主要划分为四大港区，即：董家口港区、老港区、前湾新港区以及黄岛油港区，其中董家口港区的自然条件非常优良，近海自然平均水深达到-15米,离岸一公里可达到-20米，港区的规划面积达到70多平方公里，泊位112个，计

划未来总吞吐量达到3.7亿吨。本设计是利用董家口港区的地理自然条件、水文条件等设计资料，结合港区

的地理条件、发展空间，考虑工程经济性、施工便利等方面，在董家口外围设计防波堤。在防波堤平面布置上统一采用一种方案，在结构选型上，计划采用两种设计方案，对两种方案都会进行设计验算。一种采用斜坡堤，一种采用直立堤。按规范要求直立堤会进行抗倾、抗滑验算，整体稳定性验算，地基承载力验算以及地基沉降验算；斜坡堤会进行胸墙抗倾、抗滑验算，整体稳定验算以及地基沉降计算。最后会比较选择其中一种推荐方案。

Abstract：Qingdao Port has a long history, located in China's Shandong Jiaozhou Bay, the port area of wide waters, water depth, to four seasons navigation, the overall performance of the harbor exports large belly features, is a very good port, one of China's key ports. Qingdao Port is pided into four major port areas, namely: Dongjiakou Port, Old Port, Qianwan Newport and Huangdao Oil Port, Dongjiakou Port area of the natural conditions are very good, the natural average depth of the sea to -15 meters , One kilometer offshore can reach -20 meters, the planning area of the port area of more than 70 square kilometers, 112 berths, plans the future total throughput of 370 million tons.

The design is to use Dongjiakou port area of geographical and natural conditions, hydrological conditions and other design information, combined with the port area of the geographical conditions, the development of space, considering the project economy, construction convenience, etc., in the Dongjiakou design breakwater. In the layout of the breakwater on the unified use of a program, in the structural selection, plans to use two design options, the two programs will be designed and checked. One using a slope embankment, one with a straight bank. According to the specification, the anti-dumping, anti-skid checking, the overall stability check, the foundation bearing capacity calculation and the foundation settlement check shall be carried out. The slope embankment will carry out the anti-dumping, anti-skid checking, the overall stability check and the foundation settlement calculation. Finally, we will choose one of the recommended options. The design is to use Dongjiakou port area of geographical and natural conditions, hydrological conditions and other design information, combined with the port area of the geographical conditions, the development of space, considering the project economy, construction convenience, etc., in the Dongjiakou design breakwater. In the layout of the breakwater on the unified use of a program, in the structural selection, plans to use two design options, the two programs will be designed and checked. One with a vertical breakwater and the other with a sloping breakwater. According to the specification requirements of the vertical breakwater embankment will be anti-dumping, anti-skid checking, the overall stability of the calculation, the foundation bearing capacity calculation and foundation settlement check. The sloping breakwater will carry out the anti-dumping, anti-skid checking, the overall stability check and the foundation settlement calculation. Finally, one of the options will be recommended for the comparison and selection.
