Abstract
This study investigates the suitability of an adapted portable shearing box to measure the shear-induced dilation of a discontinuity and how the basic friction angle can be reliably derived from the shear data with dilation. Results show that samples with significant roughness are required.
The reliability of the resulting basic friction angle depends on both the magnitude of the applied normal loads and the horizontal base length used to calculate the angle of dilation. We have developed data processing techniques to identify the optimal horizontal base length. The proposed method was successfully applied to estimating the basic friction angle of discontinuities that control
the blocks stability in Kaili carbonate slope.
