近年来,随着电子数字计算机的发展,桩基计算有了较大的改进。笔者就所见文献和自己的一点体会,介绍桩基计算的一种有限单元法,供同志们参考,错误之处欢迎批评指正。一、概述这里所介绍的有限单元法,是沿桩的纵轴划分为若干单元(每一单元的长度可以相等,也可以不相等,根据需要确定),藉力的平衡和位移的协调用矩阵建立方程,然后根据与所使用的电子数字计算机相适应的计算语言编制程序(如ALGOL程序语言、FORTRAN程序语言等)。
In recent years, with the development of electronic digital computer, pile foundation calculation has been greatly improved. I see the literature and my own experience, introduced a finite element calculation of pile foundation for comrades for reference, the wrong place welcome criticism and correction. I. Overview Finite element method introduced here is divided along the longitudinal axis of the pile into a number of units (each unit length can be equal or not, according to need to determine), leveraging the balance and displacement coordination matrix Establish equations and then program (eg, ALGOL programming language, FORTRAN programming language, etc.) in a computational language appropriate to the digital computer used.
