摘要:烟台港西港区是烟台众港区中最为重要港区的港区之一，其地理位置优越水深大是天然良港，但其受波浪的影响较大。而防波堤可以阻隔波浪对港区的冲击、保护港池、维持港池水面平稳、以便船舶安全停靠和装卸作业，是港口水工建筑物的重要组成部分。

防波堤形式多样，有斜坡式，直立式，特殊形式包括喷水式、喷气式、浮式等，且各有特点，研究不同形式的防波堤并进行比较从而选择最合适的方案，对烟台港西区的建设有极其重大的意义。本毕业设计选择斜坡式和直立式防波堤两种形式，分别对其进行设计计算并且进行两者的比选，主要是按照国家和行业规范的基础进行设计计算，包括防波堤的总平面布置、两种防波堤方案的断面设计、胸墙的设计计算、沉箱结构设计计算以及其抗倾抗滑稳定性的验算、地基整体稳定性与沉降量的计算。

Abstract:Yantai Port Westport is one of the most important port areas in Yantai Port Area. Its excellent geographical depth is natural harbor, but it is affected by waves. The breakwater can block the impact of the waves on the port area, protect the port, to maintain a steady pool of water for the ship to secure docking, loading and unloading operations, is an important part of the port hydraulic structures.

Breakwater has a variety of forms ,such as slope, vertical, special forms, including water spray, jet, floating, etc. and have their own characteristics, and it is of great significance to study the different types of breakwaters and compare them to select the most suitable scheme.The design and calculation of slope and vertical breakwater were designed and compared, mainly in accordance with the national and industry norms based on the design and calculation, including the overall layout of the breakwater, two breakwater program cross-section design, chest wall design, Caisson structure design and anti - tilt anti - sliding stability checking, foundation stability and settlement calculation.

Key words: Slope embankment; Straight embankment; Section design; Foundation settlement.
