摘　　要：本文根据线弹性力学的有限单元法,选用六面体单元,借助Fortran 90具有模块化、封装机制、自定义等编程特性,开发线弹性阶段的六面体单元计算程序,为计算地基沉降提出一种可行、有效的方法。并利用该方法能自行修订所需参数,以达到计算精度要求。最后,通过与ANSYS软件计算模拟地基沉降的结果比较与分析,验证其可靠性和适用性,并对比不同节点六面体单元的精确度。According to the linear elastic mechanics for finite element, this paper chose the most common hexahedral element to resort to Fortran 90 with the characteristics of modularization, encapsulation mechanism and custom to develop the program of hexahedral element in the linear elastic stage so as to propose a feasible and effective method to calculate thefoundation settlement. This method was used to revise the required parameters in order to meet the precision of the calculation. Finally, the results between this method and ANSYS simulation were compared and analyzed to verify the reliability and applicability and contrast the accuracy of hexahedral element in different nodes.
