中文摘要：

对大量的粗粒土三轴固结排水剪试验结果进行了分析,发现粗粒土的εa/（σ1-σ3）~εa,-rε/εa~-rε之间线性关系不是很好,尤其是-rε/εa~-rε的关系.进一步分析这些粗粒土试验资料后发现,分别采用双曲对数函数及抛物线函数可以很好地描述（σ1-3σ）~aε及-rε~εa之间的关系,并在此基础上建立了HLP非线性E-ν模型.采用宜兴坝堆石料、长河坝覆盖层料、双江口砾石料等的三轴固结排水剪试验结果对HLP非线性E-ν模型进行了验证,结果表明,ELP非线性E-ν模型能较好地反映粗粒土的应力应变关系.

英文摘要：

By analyzing the results of various triaxial consolidated-drained shear tests on coarse-grained soils,it was found that the linear relationships of εa/（σ1-σ3）～εa and-εr/εa～-εr were not satisfactory,especially the relationship of-εr/εa～-εr.However,the relationships of（σ1-σ3）～εa and-εr～εa could be reasonably described by the hyperbolic-logarithmic function and the parabolic function,respectively.On such a basis,a HLP nonlinear E-ν model was proposed.It was preliminarily validated by means of the results of triaxial consolidated-drained shear tests on Yixing rock-fill materials,Changheba overburden layers and Shuangjiangkou soils.The results show that the proposed model can satisfactorily depict the stress-strain relationship of coarse grained soils.
