| 摘 要： | 青藏铁路穿越高原多年冻土区546km，沿线分布着各种地形地貌单元，包括盆地、高山区、高平原、谷地等，各处的地层岩性和冻土赋存环境各不相同．通过对青藏高原多年冻土区典型土样的冻胀率试验，分析了高原多年冻土的冻胀率与含泥量、含水率、干密度之间的规律．结果表明：高原冻土具有较大的冻胀率，其冻胀率随含泥量的增加而增加，随含水率...

| Abstract: | There is a plateau permafrost area,about 546 km in length,along the Golmud-Lhasa Railway.In this permafrost area various landforms developed,including basin,mountainous,plateau and valley,with different geology and frozen soil conditions.An experimentation of frost-heaving ratio had done and the typical soil samples were taken from the permafrost area along the Golmud-Lhasa Railway.On the basis of the experimentation data,the relationships among the frost-heaving ratio,the silt content,the water content and... |
