摘　　要：为研究土石混合料高填方路堤变形特性,采用土工离心试验方法,对土石比为30∶70的土石混填料高填方路堤的缩尺模型进行试验研究。研究结果表明,高填方路堤的水平位移变形特征分为两个阶段,其中在高度10 m处出现最大水平位移;高填方路堤的垂直位移随着坡比的变大而增加,即在相同填料下,坡度越缓,沉降越小;试验所得出的高填方路堤变形特性为后续施工提供参考意见。In order to study the deformation characteristics of the high-fill embankment with soil-rock mixture,the geotechnical centrifugal test method was used to test the scale model of the high-fill embankment with soil-rock mixture with a soil-rock ratio of 30∶70.The research results show that the horizontal displacement and deformation characteristics of the high-fill embankment are divided into two stages,in which the maximum horizontal displacement occurs at a height of 10 m,the vertical displacement of the high-fill embankment increases as the slope ratio increases,that is,in the same filling the lower the slope,the smaller the settlement,the deformation characteristics of the high-fill embankment obtained from the test provide a reference for subsequent construction.
