| 摘 要： | 在工程实际中对坝体与坝基的相互作用问题进行数值模拟时经常按照一体两介质进行分析，这种假设与实际存在出入。为了研究理论与实际的差别和建立正确的分析模型提供理论依据，初步建立了一体两介质与两体两介质力学模型，并分别进行了轴向受压试验。试验结果表明，低强度介质强度与高强度介质的强度之比? 是影响一体两介质力学模型与两体两介质力学模型的重要参量，且影响程度与影响机制在不同力学模型之间存在较大的差别。

| Abstract: | In the numerical analysis for the soil-dam interaction, the bi-material model (on the interface, two materials possess the same lateral deformation ) is usually used, that causes error between analytical result and practice. In order to discuss the error and set the correct analytical model, the bi-material model and the bi-body model (relative lateral deformation is considered) are proposed. Besides, their samples were tested under axial compression. It is shown that the ratio of strengths ? between two materials is an important parameter for both models, but its effect and the mechanism on each model is different. |
