| 摘 要： | 利用已有的高速公路土工试验资料，通过大量的非线性有限元计算得出一个与路堤填筑高度及路基土体压缩系数相关的沉降综合修正式，使得单向 e-lgp 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误差较小，不但比规范法更合理，而且与实测值以及有限元法结果很接近，具有一定的工程参考价值和借鉴意义。

| Abstract: | Based on the existing soil engineering test data of many expressways, and through a lot of nonlinear finite element method calculations, a general settlement modification formula associated with filled height of embankment and soil compressive coefficient of roadbed, is put forward. This formula can cause the unilateral e-lg p method results to consider soil lateral deformation and validated by two engineering examples. The results show that the settlements modified by this formula have less errors, it is not only more reasonable than criterion method but also more closed to the measured data. In a way, this method can be used for reference in other engineering. |
