摘　　要：通过试验,从界限含水率、比重、水稳定性能、击实等方面,分析了西藏林芝粉土的基本物理力学性能,指出林芝粉土为低液限粉土,浸水快速崩解,CBR小于5%,不能直接作为二级公路路基的上路床填料。According to the tests,the paper analyzes basic physical dynamic property of the silt of Linzhi in Tibet from the water ratio limit,proportion,water stability performance,and compaction,and points out the silt of Linzhi has low liquid-limit and disintergrates rapidly in water,and its CBR is less than 5 percent,so it can not be directly used as the roadbed filler of secondary roads.
