摘　　要：本文利用差分原理推导了Terzaghi一维固结微分方程的解法,借助Matlab矩阵工具进行实现,对具体工程实例进行计算,得到符合理想情况的Terzaghi固结方程解。得到结论:对于均匀的地层,满足Terzaghi基本假设条件下,借助差分法可以得到一维固结微分方程的解;对于不满足假设条件的情况,改变初始及边界条件后,仍然可以利用差分法进行求解。The one-dimensional Terzaghi consolidation differential equation solution is derived with the difference principle. That is achieved by MATLAB matrix tool. The specific example is calculated out and the solution results in line with an ideal Terzaghi situation. The conclusion as follows： For the uniform formation, the basic Terzaghi assumptions met, differential equations of one-dimensional consolidation can be obtained with the difference methodg For the case the assumptions can not be met, changing the initial and boundary conditions, they can still be solved using the differential method.
