| 中文摘要: |
| 本文首先对作用在文献[1]所得到的一个加筋复合土体本构模型进行分析计算。并将其编制成有限元程序，分析了一个具有实测资料的加筋路堤工程实例，与实测值进行比较，检验了程序以及这个加筋复合体本构模型的可靠性。然后对某简化堤坝工程进行了沉降和稳定计算。计算结果表明，这个加筋复合体模型以及有限元程序能够合理地反映加筋效果。 |
| 英文摘要: |
| The stress and strain of a geotextile-reinforced composite embankment for highways was analyzed by using a constitutive model of FEM proposed by the authors. The validity of the model was verified with a good agreement between the calculation and field measurement. Calculation of settlement and stability were further carried out on a simplified embankment and the reinforcement effect was reasonubly reflected. |
