摘要
文章阐述了桩长差异带来的问题,提出了不等长群桩基础内力和位移计算方法及计算公式,并结合某高速公路上的一座特大桥工程实例,对文章推导的计算方法进行验证,结果表明该计算方法是可行的。
The article described the problems caused by the differences in pile length, pro- posed the internal force and displacement calculation methods and formulas for unequal group pile foundation,and in combination with a super-large bridge engineering case in an expressway, it verified the calculation method derived in this article, and the results indicated that this calculation method is feasible.
