A Port In Northern San Scheme Selection Research On General Cargo Wharf Structure

The Format Criterion of Master’s Degree Paper of DUTTechnology selection principle:to ensure the reliability, safety, both the applicability, economy.To solve the practical problems of content:according to the geological conditions of the project’s, terminal can use gravity structure, also can use pile foundation structure. Such as the use of gravity type structure, selection of silty clay layer plastic as the terminal bearing layer. Such as the use of pile foundation structure, considering the project area in freezing and ice load, pile type selection using steel pipe pile structure.The above structure is selected, the corresponding analysis function and the effect of combination ofA, effect:1permanent action:include earth pressure building weight, packing production.2The variable function:including the cargo load, mechanical load flow, door machine load, soil pressure, variable effects of ship loading and wave force.3accidental action:earthquake.B, combination of action effects:According to the structure may appear at the same time, the state according to the bearing capacity limit state and serviceability limit, combined with the design of the combination of action effects.1lasting effect combinationThe design of high, low level design, extremely high, extreme low water levels, each level combination is as follows:A:the self gravity (permanent)+soil pressure variable effects (the dominant variable function)+mooring force (non dominant variable action)The combination of two:the self gravity (permanent)+soil pressure variable effects (non dominant variable action)+mooring force (the dominant variable role)The combination of three:the self gravity (permanent) and heap loading (the dominant variable function)+wave force (non dominant variable action) The combination of four:the self gravity (permanent) and heap loading (non dominant variable action)+wave force (the dominant variable role)2short effect combinationDesign of high level, low level design, the combination of the following:The wharf is not backfill when self gravity (permanent)+wave force construction period (variable action)3accidental effect combinationDesign of high level, low level design, the combination of the following:Since gravity+50%surcharge+50%mooring force and earthquake force...
