摘要本次毕业设计拟建有 3 个 3000 吨级水泥泊位的码头。该码头位于经济发展较快 的大连市，主要用于水泥厂水泥的运输。水泥是现代城市建设与发展的主要原料，其 需求量无比巨大，因此水泥的运输量同样巨大。考虑到水泥的巨大运输量以及大连的 地理位置，水陆交通十分便利，水运成为了最为经济合理的运输方式。79359

大连地区地质条件比较好，承载力较差的淤泥层和淤泥质粉质粘土层厚度不大， 其下便是承载能力较好,能够直接使用的碎石层，可以采用挖除的方法去掉上层土， 然后将码头基底坐落在承载能力较好的碎石层上。

综合考虑大连地区的经济发展状况及其自然条件，本设计决定采用重力式码头中 的沉箱结构形式是合理的。该码头设计对波浪力、土压力及堆货荷载等各种作用力进 行了计算，并完成了抗倾、抗滑及基床稳定性验算，初步完成了码头设计。

毕业论文关键词：沉箱、结构设计、荷载、重力式码头

Abstract The graduation project is proposed to build a cement wharf with three 3000 tons cement berth。 The wharf is located in Dalian City, whose development of economy is fast。 It is mainly used for cement transportation。 Cement is the main raw material for the construction and development of modern city and its demand is very huge。So the volume of cement is also great。 Taking into the huge amount of cement and the geographical location of the Dalian, water transportation is very convenient and water transport has become the most economical and reasonable mode of transport。

The geological conditions of Dalian area are relatively good。 The silt layer and silty clay layer with poor bearing capacity are thin。 The lower is the gravel layer with better bearing capacity,which can be used directly。 The upper soil of the gravel layer can be removed directly and then the pier base can be located on the gravel layer with better bearing capacity。

In comprehensive consideration of the economic development status and its natural conditions in Dalian, this design adopted caisson gravity type wharf structure is reasonable。 The wharf design have calculated various forces such as wave force, soil pressure and heap loading of goods etc。 and the checking of anti dumping stability, anti slide stability and subgrade bearing capacity have been completed。 Design of the wharf have completed preliminarily。

Keywords: quay caisson, structure design , load, gravity wharf
