摘要

研究了不同墩梁刚度比、不同桩基刚度下的门式墩结构盖梁、墩柱、桩基内力。根据墩梁刚度比变化引起的盖梁内力及墩身次内力,给出设计建议墩梁线刚度比;根据桩基刚度变化引起的墩身内力及桩身内力,给出建议桩基模拟方法。
        The research on the internal force of cover beam,pier stud and pile foundation of portal pier under different ratios of rigidity of pier beams and rigidity of different pile foundation.The design on the suggested ratio of rigidity of line of pier beam is given according to the internal force of cover beam and secondary internal force of pier body caused by the change of ratio of rigidity of pier beam.The suggested analogy method for pile foundation is given according to the internal force of pier body and pile body caused by the change of rigidity of pile foundation.
