Question:

With reference to the generic wedge shown in the sketch and the data in Table 2.9, the water table is below the toe, vertical distance between A and O is 85 ft (25.9 m), point T is 40 ft from point A, rock specific weight is 158pcf (25.0kN/m3), and active wedge volume is 3,850 yd3 (2,944 m3).

(a) Find the dip direction (azimuth) and dip of the line of intersection of joint planes A and B.

(b) Find the range of intersection line azimuths that preclude sliding down the line of intersection.
