| 摘 要： | 基于Ducan—Chang双曲线模型，对剪切硬化粘土应力应变关系归一化性状进行了系统分析，从理论上推导了两种新的归一化因子（（σ1-σ3）血和（σc）n），并以实例进行验证，结果表明：当采用常规归一化因子不能很好地实现归一化性状时，采用新的归一化因子来归一化效果很好，值得在实际工程中推广应用。

| Abstract: | Based on Ducan-Chang hyperbolic model,systematic normalization character analysis was made for the stress-strain relationship of shearing hardening clay;new normalization factors of(σ1-σ3)ult and(σc)n were derived theoretically and were verified by actual examples.It was demonstrated that new normalization factors may render good effect when conventional factors fail to realize satisfactory normalized character,and shall be spread and applied in actual project. |
