| 中文摘要:在软土地基加筋路堤稳定性分析方法中，传统的瑞典条分法由于对土工合成材料的加筋作用存在认识上的误区，导致最终的计算结果过于保守。对软土地基加筋路堤的加固机理和破坏模式进行深入分析发现，传统分析方法对加筋体的加筋作用估计不足，据此，在充分考虑加筋体的加筋作用下，基于瑞典条分法提出了新的稳定性分析计算公式，通过实例验证该法比较符合工程实际。 |

| Abstract:Of the stability analyses of embankment reinforced by geo-synthetic material, the traditional Sweden slice method obviously owes its conservation to the misunderstanding of reinforcement mechanism of geo-synthetic material. Deep studies of the failure and reinforcement mechanism of geo-synthetic material show that the reinforcement effects of geo-synthetic material were considerably underestimated. Therefore, a new stability analysis method of embankment reinforced by geo-synthetic material, called modification of Sweden slice method, is presented by modifying the assumption of reinforcement effects. The in-situ case demonstrates the presented method is effective and practical. |
