Refer to Figure P13.9. Assume the botton 8 m to be hard rock and the following values.

Question:

qulconcrete) = 28,000 kN/m? E concrete) = 22 x 10° kN/m? E corefrock) = 12.1 X 10° kN/m? Iulrock) = 46,000 kN/m? RQDrock) = 75%

Spacing of discontinuity in rock = 500 mm

Thickness of individual discontinuity in rock = 3 mm
