摘要
在大型三轴仪上进行素碎石土和加筋碎石土排水剪切试验 ,探讨了加筋碎石土的应力 -应变特性 ;提出了塑料土工格栅加筋碎石土的E_S非线性本构关系模型 ,并确定了模型的计算参数 。
By the large_scale tri_axial test equipment, dewatering and shearing test of crushed gravel and polymer geogrid reinforced crushed gravel are carried out.The stress_strain characteristics of reinforced crushed gravel have been probed into; a nonlinear constitutive relations model is put forward; and the model's parameters are determined; it can provide scientific basis for theoretical computation.
