直立式防波堤设计项目报告
摘 要
为了很好的综合本科阶段学过的专业课程，将所学知识熟练综合运用，活学活用，而防波堤的设计能综合大多数专业课程，故本次毕业设计论文选择了对连云港新港区进行防波堤设计。
本防波堤设计严格按照国家和行业规范，借鉴现有港区防波堤的建设经验，结合连云港新港区的实际情况进行设计。设计之初搜集了大量的相关资料，在设计过程中运用了相关的计算软件。本设计对港区进行了总平面设计，对防波堤形式进行了比选，对波浪力进行计算，对防波堤的稳定性进行验算，最后出图。
经过对比计算，在连云港新港区选择了沉箱防波堤这种结构型式，并对其结构及稳定性经行了计算和验算，结果满足要求。

Abstract
In order to good comprehensive undergraduate stage studied the professional course, study the knowledge skilled comprehensive use of learning, and live, the design of the
breakwater comprehensive most professional course, can so this design graduate thesis chose to lianyungang port for breakwater design new.
The breakwater design in strict accordance with the national industry standard for
reference, and the experiences of the construction of existing port breakwater, combining with the actual situation of lianyungang port new design. At the beginning of the design gathered a lot of relevant information, in the design process using the related calculation software. The design of the port total plane design of breakwater, form of wave force than the election, calculation of breakwater, the stability of the last out, check map
By comparison and calculation, the new port area in lianyungang chose this structure types of caisson type breakwater, and its structure and stability calculation and checking the line, the results meet the requirements.
Key words： The graduation design，breakwater，stability
