Abstract: An integrated corrected formula for settlement related to compressibility of subbed soil layer and the height of earth bank is obtained by a large quantity of non-linear FEM calculation using the data from a certain freeway. After corrected by formula the calculation result from unidirectional compression index method is available to considering lateral deformation. The case study has shown that the settlement value corrected by this formula is much more approaching the observed value, error is tiny, and can be referred by other projects.

摘要： 利用高速公路资料，通过大量的非线性有限元计算，得出-个与路堤填筑高度及路基土层压缩模量有关的沉降综合修正式子，它使得单向压缩指数法的计算结果修正后能够考虑土体侧向变形。实例验证表明：经此式修正后的沉降值更接近实测值，误差很小，具有-定的工程参考价值和借鉴意义。
