摘要
通过对三组含不同粒度成分的无泥型软弱层带室内土动三轴试验 ,表明其动变形特性 ,即动应力 -动应变符合 R.L.Kondner双曲线型关系。同时所得的动弹模表现出与其试样的含水状态、粒度粗细及密实程度有密切联系 ;但对以粗碎屑为特征的无泥型软弱层带变形参数衰减程度而言 ,其动荷载效应并不明显。
Through analyzing the dynamic deformation test results of no clay weak interbed belonging to different granulometric composition, we show that relation between dynamic stress (σ d) and dynamic strain(ε d) conform to the hyperbolic curve of R.L.Kondner. Simultaneously,the dynamic modulus is correlated with moisture content, granulometric composition, and dry density of no clay weak interbed. Test results show that dynamic effect is not evident for no clay (coarse elastic soil) weak interbed.
