摘要
在充分考虑涂抹层效应的基础上,构造了一种以四结点等参单元耦合六结点等厚度接触面单元的耦合单元,来模拟排水井地基中的涂抹层,并编制了相应的有限元程序。通过程序计算分析了2个算例,计算结果合理可靠,表明构造的耦合单元模型可以有效地应用于实际工程的数值模拟。
Based on considering the effect of smear layer, 6-node constant thickness contact interface elements coupled with 4-node isoparametric elements are used to simulate the smear layer of drain wells. A relevant program is made to analyses two practical examples. The result is verified to be reasonable. It is shown that the coupled element model is effective and can be used in numerical analysis in engineering practice.
