In order to increase the maximum width to which the slope can be undercut, slope stabilization shear pins is required. In this study, two layout patterns of pencil leads, 2 mm in diameter, were placed into physical models of undercut slope made of a confined block of humid silica sand No.6 resting a Teflon plate. The soil pressure and slope movement during which the slope was undercut from the center line until reaching the failure were monitored by a set of pressure gauges, digital camera and high-speed VDO camera. The experimental results revealed that for a given similar number of pencil leads, the layout in vertical row has a higher influence on the stability than that in horizontal row.
