| 摘 要： | 结合现有不规则道路运营现状及旧路改建的趋势化，提出将旧路改建问题数学化。综合运用拟合逼近原理，建立旧路改造路线的数学模型。通过对数学模型的不断优化，得到目标线形函数，结合数值计算软件MATLAB程序，对实例模型进行试算，获得较理想的线形参数。结果表明：路线问题数学化得到的拟合参数较合理可靠，可作为相关设计的参考。

| Abstract: | Combined with the existing road reconstruction operation status of irregular and old road the trend, the problems of the old road reconstruction of mathematics are presented. According to fitting approximation principle, a mathematical model of the old road is set up. Through continuous optimization of the mathematical model, a linear function of target is obtained, and numer- ical calculation software MATLAB program, for example by trial model, obtains the linear parameter ideal. The results show that the fitting parameters route mathematic problem obtained is reasonable and reliable and can be used as a design reference. |
