密度对黄土边坡稳定性的影响及修正研究

On density's influence on loess side slope's stability and its correction

通过收集陕北和陇东地区大量的钻孔与探井试验数据,对黄土的天然密度和干密度进行了概率分布和变异性分析,论证了密度对边坡稳定系数的影响量值,提出了钻孔取样干密度的修正公式。

By collecting drilling and exploitation test wells data from the north of Shanxi and the east of Gansu,the paper undertakes the probability distribution and variability analysis of the natural density and dry density of the loess,illustrates the influential value of the side slope stability coefficient,and points out the correction formula for the drilling sample＇s dry density.
