用通用有限元程序分析精密设备基础沉降的方法

A method to calculate the settlement of the foundation of a precision equipment by general FEM

采用弹性有限元方法计算了设备对地基的附加应力 ,根据土力试验数据验算了地基的沉降 ,完成了要用专门的土力学程序分析计算的工作 ,得到满意的结果。本文的工作对于精确分析基础沉降有借鉴作用。

By means of general FEM (finite element method), the additional stress in the foundation of a precision equipment is calculated. And the settlement is determined with required precision using soil mechanic test data. Since such work is generally carried out by a special soil mechanic FEM, the work is significant for practical application and scientific inference.
