摘要:
在干旱半干旱地区，压实黄土广泛用于建造路堤、土坝、基坑回填等工程中，受降雨入渗等因素影响，压实黄土的含
水量经常会发生变化，其抗剪强度也会随之改变．通过直剪试验研究了压实黄土的抗剪强度参数随含水量和干密度的变化规
律．得出在干密度相同的条件下，压实黄土的粘聚力、内摩擦角随含水量的增大而减小的结论；归纳出粘聚力、内摩擦角与
含水量均呈二次抛物线关系．进一步分析得到了考虑含水量和干密度影响的压实黄土抗剪强度计算公式．
Abstract:
In arid and semi-arid regions, compacted loess is widely used in the construction of embankment, dam, excavation backfill
and other projects. By rainfall infiltration and other factors, the moisture content of compacted loess will change frequently; so will
the shear strength. Through direct shear tests, this paper studies the variation of shear strength parameters of compacted loess with
water content and dry density. It gives the conclusion that under the same dry density conditions, compacted loess cohesion and
internal friction angle increases with the decrease of water content; and the cohesion and internal friction angle have a quadratic
parabolic relationship with water content. Further analysis has been calculated considering the impact of water content and dry
density of compacted loess shear.
