In this technical note, an analytical investigation was carried out in order to develop simple methods to predict the plane-strain angle of shearing resistance ($$\varphi_{\text{ps}}$$φps) for overconsolidated sands using direct shear or triaxial compression test results. The proposed methods were found to be suitable for lightly overconsolidated sands (i.e., OCR ≤ 4), which represent practical range of overconsolidated ratio for granular material placed behind retaining walls. Furthermore, the predicted values of $$\varphi_{\text{ps}}$$φps, compared to the corresponding values of direct shear and triaxial tests, are within ranges of deviation similar to those noted for normally consolidated sands. |
