摘要汕头港的广澳港区位于汕头市的濠江区南端广澳湾内，东枕马耳角海岬，西接企望湾，北靠汕头市，南部面向南海，地理位置和水深条件非常优越，港区泥沙轻微有些淤积，有较稳定的地质结构，离城市中心的距离适中，是粤东唯一的天然深水良港，拥有建设30万吨级以上码头的优良水深条件。但是港区处于开敞海域，波浪条件恶劣复杂，一定程度影响了船舶进出港和靠离泊作业的安全，所以需要修建防波堤。因此本设计根据汕头港区水文地质条件及发展需求分别设计了沉箱直立式和斜坡式两种防波堤，并综合考虑两者的优缺点选择最优方案。62285
本设计根据工程所在地区的水文地质资料，结合工程建设的目的及后续发展，确定了总平面布置方案，断面型式及断面尺寸，再根据波浪情况，建筑材料及地基土性质，进行了进行斜坡堤胸墙、直立沉箱的抗倾、抗滑稳定性验算以及基床抗滑稳定性验算。对防波堤的地基整体稳定性和地基土沉降量进行计算。针对沉箱式防波堤还进行了干舷高度计算和浮游稳定性计算。同时还对直立堤的基床和地基承载力进行验算。

Abstract Shantou port Guang'ao port area is located in Shantou City Haojiang district at the southern tip of the Guang'ao Bay, East pillow Maltese headland, hope Bay is received on the west, north by Shantou City, south facing the South China Sea, geographical location and the depth of the water condition is superior, harbor sediment slightly siltation, relatively stable geological structure, away from the city center of moderate distance is Guangdong only natural deep-water harbor, has more than 30 million ton wharf construction excellent water conditions. But port located in the open sea, wave conditions complex, to a certain extent affected the ship out of Hong Kong and by unberthing operation safety, so it is necessary to build breakwater. So this design according to Shantou Port hydrogeological conditions and development needs were designed caisson vertical and slope two breakwater, and comprehensive consideration of both the advantages and disadvantages of choosing the optimum plan.
This design according to the hydrological and geological data in the areas where the construction projects, combined with the purpose of engineering construction and the subsequent development of, to determine the general layout plan, section type and section size, according to the wave, building materials and the properties of soil, sloping breakwater parapet, upright caissons of anti dumping, anti sliding stability calculation and bedding anti slide stability checking. The whole stability of the foundation and the settlement of foundation soil are calculated. The caisson breakwater is also calculated freeboard calculation and floating stability. Also on the breakwater foundation and foundation bearing capacity checking.
Keywords: Shantou port; breakwater; slope; caisson upright; layout; structure design; overall stability; settlement of foundation
