摘要
为研究加筋土结构在多年冻土区路基边坡的工程效果与适用条件,在拉萨—日喀则铁路路基边坡进行了设计并开展了试验研究,包括测定的物理力学性能指标、对土工格栅冻融及拉拔摩擦进行了试验、对现场断面的变形进行了测试。试验结果表明,加筋土结构适应路堤边坡变形,可用于多年冻土区路基边坡防护。
In order to study engineering effect and applicable conditions of the reinforced soil structure for subgrade slope protection in frozen soil area,subgrade slope protection was designed,and this paper carried out the experiment study in the Lhasa-Rikaze railway,including measurement of physical dynamics indicators,the geotechnical grille freeze-thaw and pulling friction test,the on-site cross-section deformation test. Experimental results show that reinforced soil structures adapt to the deformation of embankment slope,which can be used in permafrost area.
