| 摘 要： | Ｇｏｏｄｍａｎ教授提出的节理单元模型被广泛地应用于岩石力学与工程实践。然而该模型的分析精度却依赖于对节理的法向刚度ｋｎ切向刚度ｋｓ的准确确定。但这项工作在实验室几乎是不可能的。文中提出了一种在现场利用声波测试ｋｎ和ｋｓ的方法，并讨论了影响ｋｎ、ｋｓ测试精度的因素。

| Abstract: | The joint element model proposed by Goodman is widely used in rock mechanics and rock engineering. The accuracy of the modeling is, however, depend on the proper determination of the joint stiffness K n and K s, which is very difficult to get in lib test. A method is proposed in this paper to calculate K n and K s by the field supersonic wave test. |
