考虑中主应力的邓肯模型

DUNCAN MODEL OF REFLECTED ON MIDDLE PRINCIPAL STRESS

根据双剪应力理论对邓肯模型进行了修正。修正模型考虑了中主应力的影响,既在形式上保持了邓肯模型简单、实用的特点,又在应用上拓宽了邓肯模型的应用范围。通过实例计算,取得了比较满意的结果,验证了修正模型的可行性。

According to the twin shear stress theory, this paper improves on Duncan Model. The revised model reflectes upon the middle principal stress and preserves the form of Duncan Modol, but it widens the application ges of Duncan Model. The result of the example calculation is satisfying.
