中文摘要：
原始统一硬化模型是基于在等向压缩条件下土的比体积与压力的对数呈线性关系而建立的。由于v-Inp线性关系在理论上存在某些不合理，Hashiguchi等建议采用Inv-Inp线性关系以消除这些不合理性。基于此，推导出基于等向压缩的Inv-Inp线性关系的统一硬化模型，并通过对两个模型分别进行试验结果与预测结果的比较，结果表明：在一般条件下两个模型都能合理描述土的应力应变特性，差别不大。
英文摘要：
The original unified hardening model （UH model） is established based on the linear relation of v -Inp under isotropic consolidation. As the linear relation of v - Inp has some theoretical shortcomings, a modified UH model is deduced based on the linear relation of Inv - Inp proposed by Hashiguchi et al, which is proved to be more reasonable for soils. The predicted results of the two models are compared. They are very similar. The disadvantages of the original model cause little error under common conditions only.
