| 摘 要： | 邓肯 -张非线弹性模型共有 8个参数 ,依据试验数据并按比例分别增减每个参数后 ,用有限元法计算一座土坝的应力应变等。每个参数的增减变化 ,都将引起应力应变的相应变化 ,有的成倍变化。本文结果对模型参数测试、计算取值、计算结果的综合判断具有参考价值

| Abstract: | Duncan Chang model includes eight parameters.According to tests,data analysis and computation,besides k the other seven parameters vary within limits of 10%～40%,and cause 10～100 percent variety of computed displacements.While the k value may be changed to ten times because of measurement accuracy,the displacements will be also changed within ten to hundred percent.In the example of an earth dam with height of 31 m,the changes of the displacements and stress ratio are computed with each of the parameters increased or decreased 20 to 25 percent from test data.The results can be used as reference for test of model parameters and analysis of computed results. |
