| 摘 要： | 利用Matlab6.1平台，通过编制可视化应用程序，对分层总和法计算沉降的传统方法作了较大的改进，地基中的附加应力采用原始积分公式，压缩曲线采用双曲线形式，使用非线性最小二乘法进行拟合处理，压缩层计算深度与分层厚度不再受到限制，数据输入、输出及沉降计算过程均通过可视化界面进行操作，不再需要通过查表、查图计算基础底面的沉降，计算过程简单便利，计算结果重复性好，具有较大的实际应用价值。

| Abstract: | Using Matlab6.1 platform and related visual program language, several promotions are presented to calculate foundation settlements by layerwise summation method. Initial additional stress formula and nonlinear least square method are used to calculate soil’s stress and void ratio, respectively. The settlement calculation depth and each layerwise thickness would not be constrained. Data’s input and output, calculate procedures are operated visually. The foundation settlement can be calculated out not by tables and figures but by visualization. It is shown that these promotions are practical to compute foundation settlement. |
