摘要
本文分析了Biot固结方程的不对称性,从变分原理和虚位移原理的角度建立了固结问题的有限元方程式,研究表明固结问题的有限元方程式的系数矩阵是不对称的。
The asymmetry of Biots equation is studied, and the linear equations to solve Biots equations by finite element method are established according to variational theorem and virtual displacement theorem. It is shown that the matrix of linear equations to solve Biots equations by finite element method is asymmetric.
