摘要：本研究的目的是实现一种独立的桩基加筋土结构，可应用于挡土墙等结构，以及在斜坡等狭窄施工场地修建的路堤崩塌或落石冲击对策。为证实土工格栅将桩基础应用于加筋土结构提高结构抗侧力的有效性，并研究桩与加筋土结构之间的相互作用，进行了动力离心模型试验（25 G）。为了减少建在斜坡上的路堤在地震时的变形，采用了一种有桩和一种无桩的两种土工格栅加筋土，并考虑了桩基础对加筋土结构对路面影响的有效性。描述了动力离心模型试验的细节和结果，以及桩与加筋土结构之间的相互作用，并讨论了桩基在加筋土结构中应用的有效性。
ABSTRACT Our aim in this study was to achieve an independent reinforced soil structure with pile foundation that can be applied to such structures as earth retaining walls and countermeasures against the collapse of embankments or rockfall impact built on narrow construction sites, such as on slopes. In order to confirm the effectiveness of the application of pile foundation to reinforced soil structures by geogrid for improvement of the lateral resistance of the structure and to investigate the interaction between pile and reinforced soil structure, a dynamic centrifuge model test (25 G) was carried out. Two geogrid reinforced soil, one with piles and one without, were used in a countermeasure to reduce the deformation of a road embankment built on a slope in the event of an earthquake, and the effectiveness of the pile foundation to the reinforced soil structure was considered with regard to it affected the road surface. The details and the results of the dynamic centrifuge model test, as well as the interaction between pile and reinforced soil structure are described, and the effectiveness of the application of pile foundation to reinforced soil structure is discussed in this paper.
