高速铁路路基沉降是一个复杂的系统过程,涉及不同时期、不同工况,选用单一的预测模型不足以反映路基整体的变形规律.Logistic模型及Verhulst模型的曲线均为S形,可以反映全过程的地基沉降与时间的关系.针对路基填筑期和降水期两个时段利用MATLAB软件编制程序计算模型参数,得到Logistic模型和灰色Verhulst模型,进而求得两者的最优加权组合模型.对比结果表明:在路基填筑期由两者的最优加权组合模型预测得到的结果与实测结果较吻合,拟合精度高于单一模型 而在降水期Verhulst模型的预测值更接近实测值,平均相对误差约为1.75％,拟合精度较高.(High-speed railway subgrade settlement process is a complex system involving different times and in different conditions, the choice of a single forecasting model does not adequately reflect the overall deformation of roadbed. Curve Logistic model and Verhulst models are S-shaped, the whole process can be reflected foundation settlement versus time. against roadbed construction period of two hours and precipitation using MATLAB software programming model parameters, the Logistic model and gray Verhulst model, and then get the optimal model of a weighted combination of the two. comparative results indicate : results and experimental results in the roadbed construction period by the weighted combination of the best of both models predicted than the anastomosis fitting accuracy than a single model precipitation predicted value of Verhulst model closer to the actual value of the average relative error approximately 1.75 fitting accuracy.)

tep 1：对遗传算法的运行参数进行赋值。参数包括种群规模、变量个数、交叉概率、变异概
率以及遗传运算的终止进化代数。
Step 2：建立区域描述器。根据轨道交通与常规公交运营协调模型的求解变量的约束条件，设
置变量的取值范围。
Step 3：在Step 2的变量取值范围内，随机产生初始群体，代入适应度函数计算其适应度值。
Step 4：执行比例选择算子进行选择操作。
Step 5：按交叉概率对交叉算子执行交叉操作。
Step 6：按变异概率执行离散变异操作。
Step 7：计算Step 6得到局部最优解中每个个体的适应值，并执行最优个体保存策略。
Step 8：判断是否满足遗传运算的终止进化代数，不满足则返回Step 4，满足则输出运算结果。
其次，运用遗传算法工具箱。(Matlab genetic algorithm toolbox)
