中文摘要：
一个逐渐地非线性的发育不全的组成的模型被介绍，没有求助，它在象收益表面，塑料潜力和变丑的分解那样的 elastoplasticity 理论被开发到这些概念进有弹性、塑料的部分。岩石上的排干的测试充满的 Triaxial 在压力路径的二种类型下面在一台大规模 triaxial 仪器上被进行，它与过渡特征是经常的压力比率的压力路径和复杂压力路径。由压力路径的效果激发了， Gudehus-Bauer 发育不全的模型被与应力的不同比率认为参数是变化改进增长。恰当的参数 α 与即时压力路径决定的斜坡角度 θ 的余弦介绍一片明智的线性关系。改进发育不全的模型能介绍山峰应力增加并且容量的紧张随过渡限制压力 σ 3t 的增加和压力路径的斜坡角度 θ 的减少从膨胀性改变到 contractancy。与测试数据相比，模型能够充分在岩石上考虑压力路径的效果，这被显示出充满。
英文摘要：
An incrementally nonlinear hypoplastic constitutive model was introduced, which was developed without recourse to the concepts in elastoplasticity theory such as yield surface, plastic potential and the decomposition of the deformation into elastic and plastic parts. Triaxial drained tests on rockfill were conducted on a large scale triaxial apparatus under two types of stress paths, which were the stress paths of constant stress ratio and the complex stress paths with transitional features. Motivated by the effect of stress path, the Gudehus-Bauer hypoplastic model was improved by considering the parameter variations with different ratios of stress increment. Fitting parameter a presents a piecewise linear relationship with cosine of the slope angle θ determined by instantaneous stress path. The improved hypoplastic model can present peak stress increasing and volumetric strain changing from dilatancy to contractancy with the increase of transitional confining pressure σ3t and the decrease of slope angle θ of stress path. Compared with the test data, it is shown that the model is capable of fully considering the effect of stress path on rockfill.
