| 摘 要： | 针对软土路基沉降变形的特点,分别采用传统的规范中经验系数校正法,不考虑蠕变特性及考虑蠕变特性的有限元方法分析了路基的沉降变形,研究结果表明:路堤填土荷载较大时,且软土路基蠕变性质比较明显时,不适宜采用传统的规范方法计算路基沉降,而采用考虑蠕变影响的有限元分析方法可能更加合适。

| Abstract: | According to the characteristics of subgrades of soft clay,settlement deformation rules research of subgrades were studied respectively by traditional experiential coefficient revise method in Technical Specifications,and considering consolidation creep properties in the FEM method.These work can be used for reference in study the settlement deformation of subgrades under the complex geological conditions.The result show that,when the embankment backfill load is bigger and the creep character of subgrades is obvious,it is not feasible to calculate the subgrade settlement by traditional method in Technical Specifications while the creep calculation in FEM method are more suitable. |
