水平荷载下底梁式全直桩码头横向荷载传递规律

针对常规内河全直桩高桩码头抵抗水平力差的缺点,提出了底梁式全直桩高桩码头结构,并对此结构进行了室内模型试验和数学模型试验.在室内模型试验中首先利用方程分析法和量纲分析法作相似分析,得到试验模型相似参数,然后通过一系列的前期土工模型试验对模型材料进行配制和选定,并在此基础上进行水平荷载作用下的码头结构-桩-土的试验.通过对比分析两种方法在水平荷载作用下结构的桩身位移、应变、弯矩和剪力,以及横梁和靠船梁的轴力,从而探讨结构的横向荷载传递规律.结果表明底梁式全直桩码头能较好地抵抗水平力的作用,可供同类工程设计参考.

Experimental studies on load horizontal transfer of mudsill all-vertical-piled wharf under horizontal force

In view of the poor characteristic of conventional all-vertical-piled wharf’s ability of resisting horizontal loads,this paper introduces a new type of structure named mudsill all-vertical-piled and high-piled wharf,which is researched by geotechnical model tests and numerical simulation tests.In the geotechnical model tests,similarity theory analysis is applied to make sure that the similarity parameters of the test model are obtained by using equation analysis and dimensional analysis.Then the model materials are choen by a series of prophase geotechnical model tests.For the above-mentioned works,wharf structure-piles-soil test under the horizontal displacement is conducted.By comparing the results of above two methods,the displacement,strain,bending moment and shearing force of the mudsill all-vertical-piled and high-piled wharf structure,and the shaft force of the beam and mooring beam are analyzed.Thereby,the horizon loading transfer rule of this new type of a single bent structure is discussed.The results show that the new type of structure has better resistance properties to horizontal load and can be used as a good reference for the design of similar projects.
