• panels. <br />(6) Maximum range of tilt in terms of Sm/d; values of 2.2 to 2.3 Sr„/d are obtained from the graph in Figure 5. <br />?7) Maximum range of horizontal strain in terms of Sr„/d; values for tensile (positive) strain of 1.2 to 1.4 Sr„/d and <br />compressive (negative) strain of -1.2 to -1.5 Sr„/d are obtained from the graph in Figure 5. <br />(s) Maximum crack depth (in feet) in bedrock predicted to locally occur on or near steep slopes and ledges in the <br />Minnesota Creek and Lick Creek drainage areas and above barrier pillars and rigid chain (gate road) pillars. The <br />first depth range (1) is for bedrock sloping less than, or equal to, 30 percent; the second depth range (2) is for <br />slopes more than 30 percent. Add 5 to 15 feet where thick, brittle sandstones occur in ridges and near cliffs. No <br />cracks are predicted to occur in alluvium. No cracks are predicted to occur at the surface of colluvium thicker than <br />about 10 feet. <br />(9) Angle measured from a vertical reference. <br />• <br />•
