摘    要:
该文对双曲线回归拟合法和指数曲线拟合法进行探讨,采用线性和非线性最小二乘法为原则,对徐宿高速公路断面的实测沉降资料进行迭代分析并从推理结果的比较中说明二种方法的特点。结果证明采用双曲线法计算压缩性高,次固结影响较大的软土较为准确。

关 键 词:软土地基  最终沉降  双曲线法  指数曲线法

Abstract:
The paper makes research on the hyperbolic fitting method and the exponential fitting method which are based on linear and nonlinear LSE and illuminates features of the two methods from comparison of the deduction results on the analysis about observed data for some section of Xuzhou-Suqian expressway.The result proves hyperbolic fitting method is more accurate to calculate soft clay settlement with high compressibility and being affected greatly by hypoconsolidation.
Keywords:soft clay basement  final settlement  hyperbolic fitting method  exponential fitting method
