风成砂的室内静力试验研究
-
摘要: 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。Abstract: Routine labortory tests are done for blown sand,static-triaxial test is done for dry and saturated sand. The triaxial test data have been treated using regressive analysis method* It is stated clearly that the (σ1-σ3)-ε% curve of blown sand fits closely with the Duncan-chang no-linear model.
