本文选题：码头结构 + 方案比选　；参考：《大连理工大学》2014年硕士论文

【摘要】：技术比选原则：确保安全性、可靠性,兼顾经济适用。研究内容要解决的实际问题：根据研究项目所处的地质条件,码头可采用重力式结构,也可采用桩基结构。如采用重力式结构,选择可塑的粉质粘土层作为码头持力层。如采用桩基结构,考虑到本工程区域内存在冻融和冰荷载,桩型选择采用钢管桩结构。论文对上述结构进行比选,相应作用与作用效应组合的分析。一、作用： 1.永久作用：包括建筑物自重、填料产生的土压力。 2.可变作用：包括船舶荷载和波浪力、堆货荷载、门机荷载、流动机械荷载、可变作用产生的土压力等。 3.偶然作用：地震作用。二、作用效应组合：按承载能力极限状态和正常使用极限状态,根据结构可能同时出现的作用,结合相应的设计状况进行作用效应组合。 1.持久效应组合水位取设计高、设计低、极端高、极端情况下的低水位,各水位组合如下：组合一：自重力(永久作用)+可变作用产生的土压力(主导可变作用)+系缆力(非主导可变作用) 组合二：自重力(永久作用)+可变作用产生的土压力(非主导可变作用)+系缆力(主导可变作用) 组合三：自重力(永久作用)+堆载(主导可变作用)+波浪力(非主导可变作用) 组合四：自重力(永久作用)+堆载(非主导可变作用)+波浪力(主导可变作用) 2.短暂效应组合水位取设计高、设计低,各水位组合如下：码头后方未回填时自重力(永久作用)+施工期波浪力(可变作用) 3.偶然效应组合水位取设计高、设计低,各水位组合如下：自重力+50%堆载+50%系缆力+地震力
[Abstract]:Technical comparison principle: to ensure safety, reliability and economic applicability. According to the geological conditions of the research project, the wharf can adopt gravity structure or pile foundation structure. If gravity structure is adopted, the plastic silty clay layer is chosen as the wharf bearing layer. If pile foundation structure is adopted, considering the freeze-thaw and ice load in the engineering area, the steel pipe pile structure is chosen for pile type selection. In this paper, the comparison and selection of the above structures and the analysis of the combination of the corresponding action and the action effect are carried out. I. role: 1. Permanent action: includes the weight of the building, the earth pressure caused by the filler. 2. Variable action: including ship load and wave force, load, portal crane load, mobile mechanical load, variable action of earth pressure, etc. 3. Accidental action: earthquake. Second, the combination of effects: According to the limit state of bearing capacity and the limit state of normal use, combined with the corresponding design condition, the combination of action effect is carried out according to the possible simultaneous action of the structure. 1. Lasting effect combination The water level shall be high in design, low in design, extremely high in design, and low in extreme circumstances. The combination of each water level shall be as follows: Combination I: Earth pressure (leading variable action) cable force (non-dominant variable action) resulting from variable action of gravity (permanent action) Combination 2: Earth pressure (non-dominant variable action) from the variable action of gravity (permanent action) mooring force (leading variable action) Combination 3: self gravity (permanent action) surcharge (dominant variable action) wave force (non-dominant variable action) Combination 4: self gravity (permanent action) surcharge (non-dominant variable action) wave force (dominant variable action) 2. Transient effect combination The design of water level is high and the design is low. The combination of each water level is as follows: Self gravity (permanent action) wave force during construction (variable action) when unbackfilled at the rear of wharf 3. Accidental effect combination The design of water level is high and the design is low. The combination of each water level is as follows: Self gravity 50% surcharge 50% cable force seismic force
