The Yip Kan Street failure of July 1981 (Hencher, 1981) illustrates the importance of weathering on the shear strength of rock joints. The failure took place on a dry day on daylighting joints that were in some areas only dipping at about 20 degrees (Figure 44). The parent rock is a coarse-grained quartz syenite.
