摘要
m法是《桩基规范》(JGJ94 94)推荐采用的桩土共同工作分析的方法,其最常见的解法是幂级数法。本文采用m法方程的另一数值解法———有限差分法,对幂级数法不适用的弹性中长桩和特长桩的桩身内力和变形进行了分析研究,并对桩身内力分布情况进行了讨论。结果表明,差分法可很好地求解工程中的弹性中长桩和特长桩问题,且精度满足工程需要。
m method is recommended to analysis the laterally pile working together with foundation soil by 《Architectural pile foundation design code》(JGJ94-94).It's most familiar method is power series method.In the paper,to use another numerical value method,finite-difference method,to solve internal force and deformation of elastic middle long pile and much longer pile which can not be solved by power series method.At same time,to discuss internal force distribution of the pile body.Contrasted the result,it is showed that the calculation precision of finite-difference method is suitable for engineering design and the method can analysis very well of elastic middle long pile and much longer pile.
