摘要
针对胶凝材料含量大于30 kg/m3的超贫胶结材料应力应变曲线达到峰值后呈软化形态的问题,采用虚加刚性弹簧法,建立具有软化特性的超贫胶结材料的本构模型,确定了模型相应的参数,给出了该模型的一个应用实例,为超贫胶结材料的非线性分析奠定了基础。
The over lean cemented material with the content of cementing material over 30kg/m^3 shows a softened form when the peak of its stress-strain curve is reached. In consideration of the above fact, a constitutive model for the over lean cemented material with the softening characteristics was developed by use of the virtual rigid spring method, and the parameters for the model were determined. Then an example of the application of the model was given. The study provided a basis for nonlinear analysis of the over lean cemented material.
