【摘要】 我国自北至南，蜿蜒有1800km的海岸线，因此港口码头的建设对我国开发海上运输潜力、扩大对外交流和贸易、繁荣经济起着至关重要的作用。梁板式高桩码头是高桩码头的主要形式之一，在近几十年的使用过程中出现了很多影响码头正常使用的问题，甚至导致有些码头不能使用。出现这些问题的原因一直是国内外学者关心的问题，而高桩码头柔性桩基础的设计理论——简化计算方法的适用条件是导致高桩码头出现问题的主要原因之一。本文在介绍了柔性高桩承台有限单元法和有限差分程序的基本理论的基础上，以江阴某码头的实际资料为原型，采用柔性高桩承台有限单元法和FLAC^3D有限差分程序分别对受横线荷载作用下的高桩码头柔性高桩承台和桩基进行分析，得到了每根桩的轴力、剪力、弯矩、位移和转角并且与简化计算方法得到的结果进行比较，阐明了每种算法的适用条件，指出了简化计算方法在一定条件下的不合理性，这对高桩码头柔性高桩承台和桩基的设计又一定的借鉴作用。更多还原

【Abstract】 There are 1800km coastline in our country, so the construction of ports is important to our economy. Some matter which influenced the normal use of the high-piled slab and girder wharf has happened in recent years. Even some wharf s destroyed. The reason which caused the matter has been paid a lot attention by the scholars at home and abroad. In this way, the design theory of pile foundation of high-piled wharf, the method of simple calculation is one of the main reason which induced the matter. This paper bases on the introduction of the theory of the finite element method of flexible high-piled deck and FLAC3D program of finite difference method .Then, using the finite element method of flexible high-piled deck and FLAC3D program of finite difference method to analyze the transverse bent of high-piled wharf on which acts a horizontal force. And, compare the result of axes force, shearing force, bending moment, displacement, corner with which derived from the method of simple calculation. This paper illustrates application conditions and indicates the irrationality of the method of simple calculation. It may be helpful to the design of high-piled deck and pile foundation.更多还原
