| 摘 要： | 软土路基在外荷载作用下的沉降在时序上常表现复杂的非线性,本文采用抛物线模型预测软基的沉降趋势。针对简单遗传算法存在的问题,进行了大量改进,改进后的遗传算法能有效克服传统方法易陷入局部极小的缺陷,大大提高算法的搜索效率、精度和稳定性。实践表明该方法是一种有效可靠的沉降预测新方法。

| Abstract: | The settlement of soft soil ground often manifests as a nonlinear feature. The settlement curve is close the parabola to predict trend of settlement in this paper.This method is advanced genetic algorithm.It can avoid local minimum value.It is a global optimal algorithm.This method is better than the simple genetic algorithm. |
