Abstract


Ours is a relatively resource-poor countries, along with China's sustained rapid development of foreign resources, especially oil and other primary energy demand is growing. Such long-distance sea transport bulk cargo, using very large ship with a very clear economic advantage, for the construction of a large open plan with which to adapt to deep water dock is imminent. Pile - Gravity composite structure, is a promising new type of open-deepwater wharf structure, but currently in the country has not yet formed a mature technology. In this paper, Dalian, Xingang new 300,000-ton (and by 450,000 tons) of imported crude oil terminal project to pile - Gravity composite structure dolphins for the study, according to the project site conditions and requirements of the composite structure in accordance with the specification checking and optimization calculations. Calculate the main contents are: load calculation, the overall stability of the structure checking, checking bearing capacity steel concrete piles, pile and caisson node stress calculation and analysis. By checking the above, summed up this structure calculations and applicable conditions, according to the results of the initial program checking optimize give safe and practical structure of the program, the actual commencement of the project to provide technical support. In practical engineering solutions, based on the structure were investigated composite vertical piles and composite structure optimization raking piles law of universal significance proposed formulas and algorithms, summed applicable at depths greater than 25m of the pile - Gravity composite structure optimization principles and reference types. Straight pile composite structure of the main contents are: caisson size optimization proposed rule and gives the recommended dimensions, lower gravity made permeable pile foundation and reasonable demarcation point between the structure determination methods and formulas are given different heights caisson Recommended pile size and pile stress variation, summed up the pile bearing capacity of the connection point with the caisson variation. Inclined pile composite structure on the main contents are: caisson size optimization proposed rule and gives the recommended dimensions, raised pile stress variation, as well as programs and raking piles composite pile composite straight comparison of all aspects of the program. Finally next step is to study and solve the problem, our open-composite structure design and construction of deep-water pier has some reference value. Studied in this paper can be applied to the new wharf structure open-large terminal, replace the current traditional gravity and high-pile wharf structure type, promote China's outward sea port construction, further development of deep water, so that our coastline tension be extended, the larger improve economic efficiency.
