IN-SITU SHEAR TEST OF SOIL-ROOT SYSTEMS

A series of in situ tests were performed on soil root systems, and the results were analyzed with the soil-root interaction model described in a companion paper (Wu et al. 1988). The condition in the in situ test is then compared with that along a potential slip surface in a stability analysis and the test results were used to estimate the shear strength along such a slip surface. It was found that the estimated strengths are close to the measured results. Root forces estimated with the analytical models are in general agreement with measured forces and observed behavior. The estimation is discussed of the shear strength of the root-reinforced soil along a potential slip surface in a slope stability problem.
