采用三种常用的经验方法：Fredlund等人的方法（1996年出版），Vanapalli等人的方法（1996年出版）和Khalili和Khabbaz方法（1998年出版）对非饱和抗剪强度的预测进行了全面的研究。使用这些程序对文献中发表的15种土壤的抗剪强度数据进行了检查。不同土类的非饱和抗剪强度的实测值和预测值之间的比较。文中还讨论了应力状态对抗剪强度预测的影响。
Comprehensive studies on the prediction of unsaturated shear strength were performed using three commonly used empirical procedures: Fredlund et al. approach (published in 1996), Vanapalli et al. approach (published in 1996), and Khalili and Khabbaz method (published in 1998). Shear strength data published in the literature for 15 soils were examined using these procedures. Comparisons between measured and predicted values of unsaturated shear strength are presented for different soil types. The effect of stress state on the prediction of shear strength is also discussed.
