| 摘 要： | 从准粘聚力原理和张力膜效应方面,分析路堤下加筋垫层对地基土受力性能的改善,通过定量分析,揭示尺寸效应对张力膜效应和应力扩散作用的影响。研究表明,路堤下加筋垫层对地基承载力的改善和提高,主要是筋材与土界面的摩擦作用产生的准粘聚力,当垫层宽度较大时,张力膜效应和应力扩散作用甚小。

| Abstract: | This paper analyzed the influence of the geosynthetic-reinforced cushion to the ground supporting capacity through the quasi-cohesive force and the tensile membrane function,and revealed the influence of the size effect to the tensile membrane effect and the stress diffusion function through the quantitative analysis.Studies show that the improvement and enhancement of the foundation bearing capacity under embankment is mainly the pseudo-cohesion generated by interface friction between geo-synthetics and soil.When the cushion width is large,the tension membrane effect and stress diffusion is very small. |
