本文对风成砂进行了室内常规试验，分别对饱和和干燥状态的砂进行了静力三轴试验。采用回归分析的方法对三轴试验数据进行了处理。结果表明：风成砂的（σ１－σ３）－ε％曲线完全符合邓肯——张非线性变形模式。
In this paper, the conventional experiments on eolian sand were conducted, and the static and triaxial tests were performed on the saturated and dry sands. Triaxial test data was processed using regression analysis. The results show that the (σ1-σ3)-ε% curve of eolian sand fully conforms to the Duncan-Zhang nonlinear deformation model.
