摘　　要：本文采用简单方法推估计算邓肯一张双曲线模型的8个参数．使路堤沉降计算考虑土体非线性应力应变分析成为可能。同时采用超单元交换法自动创分路堤与路基的有限元网格，使高级公路的路堤沉降计算实用化。The paper calculates eight parameters of DengKen-Zhang hyperbola model by using a simple method so that embankment settlement calculation can considers the monlinear stress-strain analysis of soil body. At the same tirne, the paper cut open autonlatically the finite e1ement network of the embankment and subgrade so that th ernbankrnent settlenlent calculatlon of high-type highway will be practical by using superunit transformation method.
