| 本文简要介绍了作者提出的接触面损伤模型，推导了接触面单元的三维有限元格式。将损伤模型接触面单元应用于三维有限元计算，对滑块问题进行了数值试验，比较了不同接触面模型的计算结果，验证了接触面损伤模型分析土-结构相互作用问题的合理性和优越性。文中对一围堰工程进行了有限元分析，计算结果合理可靠，表明本文提出的损伤模型接触面单元可以方便地应用于实际工程问题的数值模拟。 |
| 英文摘要: |
| The damage interface model proposed is briefly introduced and the implementation of 3-D interface element is discussed.The slippage problem is analyzed and the rationality and advantage of the model are demonstrated by comparison of calculation results of different interface models.In addition,the deformation and stress of cutoff wall in a cofferdam are analyzed and the result is verified to be reasonable.It is shown that the damage interface model is able to well describe the problems of soil-structure interaction and can be used in numerical analysis in engineering practice. |
