软土路基的过程化设计和沉降变化趋势面的最小二乘拟合

提出了软土路基设计为过程化设计的概念，在此基础，采用最小二乘拟合数学方法，建立软土路基沉降变化趋势面实用模型的过程和方法，并给出实例，为进一步运用时间序列分析方法定量研究沉降趋势，实现工后沉降量的精确预测和控制模型的建立，以及在计算机上实现三维量化分析奠定基础。

Coursize Design of Soft Soil Roadbase and Least Square Fitting for Trend Extension of Earth Subside Change

This article gives a concept of coursize design of soft soil roadbase, then, submits an acourse and method of building a practical model of trend extension of earth subside change by using the method of least square fitting, and takes an example. They lay a foundation for using further the method of time alignment analysis to study trend extention of earth subside change, realizing accuratelly pre calculate quantity of earth subside after construction, establishing a control model, and realizing 3 dimension quantification analysis on computer.
