| 摘 要： | 某高速公路高填方路堤下的深厚软基，采用以塑料板排水为主，配合机织土工布加筋砂垫层进行了软基处理，在对有加筋砂势层和无加筋砂势层的软基变形性状进行比较的基础上，评价了加筋砂垫层的作用及效果，还通过计算，分析了机织土工布的预 应变对路基稳定性的影响，从而说明施工加筋砂垫层时，对加筋材料旗加预应变的重要性。

| Abstract: | The soft foundation under a freeway compacted by high fill was treated mainly by drainage with plastic plates cooperated by woven geotextile-reinforced sand cushion. Based on the comparison of the deformation behavior of soft foundation of both reinforced sand cushion and ordinary sand cushion,the role and effect of the reinforced sand cushion were evaluated. At last,the effect of the prestrained geotextiles on the stability of the embankment was analyzed through calculation,thus the importance was shown of the prestrain in construction. |
