【摘要】 以某大桥辅航道通航孔桩基础为工程原型，根据“ｍ法桩－弹性承台”计算方法编制了计算程序，通过大量的计算，研究了承台厚度、桩的布置形式、桩的出露长度等因素对弹性高承台─桩基础内力和变形的影响，揭示了各种因素对弹性高承台─桩基础内力和变形的影响都是通过改变承台刚度来实现的，并通过模型试验验证了这一规律。工程实践中，按照弹性承台来设计更加科学合理，符合实际情况。更多还原

【Abstract】 The high pile foundation of a bridge designed by the "m" method is proposed. The pile cap is assumed as an elastic body. The internal force and deformation of a high pile foundation with a pile cap are effected by many factors. Those are the thickness of pile cap, pile arrangement, and exposed pile length. It was found that all these factors were influenced by the ri- gidity of a pile cap. It was also verified by the model test. It is more reasonable and feasible to regard the pile cap as an elas- tic body. Finally, there are some useful conclusions.更多还原
