烟台蓬莱港防波堤工程设计摘要 蓬莱港区海岸线具备良好的建造深水泊位的条件，但受波浪的影响较大，在没有良好的掩护和依托条件下，规划通用泊位区和客滚泊位很难实施和进一步发展，所以港区发展的当务之急就是按照规划建设防波堤，构筑环抱式港池，为港区发展提供条件。根据港口的使用要求、规模、船型和当地的自然经济条件，经技术经济论证，并结合当地自然资料选择双突堤口门的总布置方案，又根据水深和控制波向选择一个最不利截面进行断面设计，初步确定了斜坡式和直立式防波堤两种方案进行比选，由波浪情况、建筑材料及地基土性质，进行了胸墙，沉箱的抗倾、抗滑稳定性验算，地基整体稳定性以及地基土沉降量的计算。关键词:防波堤，泊位，双突堤口门Breakwater Design of Penglai Harbour,Yantai CityLan Jing(College of Harbour, Coastal and Offshore Engineering, Hohai University, Nanjing, Jiangsu,210098,China)AbstractCoastline of Penglai Harbor has beneficial conditions for the construction of deep-water berths, but it is greatly affected by the waves. Without a good cover and base, it is very difficult to implement and to develop general berth area and roll-off berth. Above all, the priority of Penglai Harbor’s development is to build breakwaters and to encircle the basin in accordance with the planning. These measures are supposed to provide conditions for the Harbor development to some degree. In the process of choosing twin jetties general arrangement, lots of aspects have been taken into consideration, including requirements of usage of the Harbor, scale of the Harbor, types of ships, local economic situation and local natural environment. In addition, technical and economic feasibility has also been applied in the process. The following step is to design the fracture surface by selecting the most unfavorable cross-section in terms of water depth and controlling wave direction. Finally, two approach—sloping breakwater and vertical break...
