A 15m wide and 15m high 30m long underground storage facility is excavated in a massive limestone rock mass (with few random long joints). The long axis of the excavation is oriented N50°W. Traces of two major joint sets are identified as following: Joint A: plunge of trace of the joint on east wall is 29°S; trend of the line of intersection of the joint on the roof is 20°. Joint B: plunge of trace of the joint on east wall is 36°N; trend of the line of intersection with the roof is 286°.

Question

A 15m wide and 15m high 30m long
underground storage facility is excavated in a
massive limestone rock mass (with few random
long joints). The long axis of the excavation
oriented N50°W. Traces of two major joint sets
are identified as following:
Joint A: plunge of trace of the joint on east
wall is 29°S; trend of the line of
intersection of the joint on the roof is 20°.
Joint B: plunge of trace of the joint on east
wall is 36°N; trend of the line of
intersection with the roof is 286°.

The following figure shows a section of an anchored retaining wall embedded into a saturated stiff clay layer. The sand has a unit weight of = 18 kN/m³, c' = 0 kPa and o' = 34º. The clay has a unit weight of = 20 kN/m³, c₁ = 80 kPa and = 0°. A uniform pressure of 40 kPa is applied on the soil surface. The short term stability of the wall is considered in an undrained analysis. Use the Rankin's theory of lateral earth pressure to determine the active and passive horizontal stresses. You should apply the requirements of AS 4678 and the partial factors of safety method in estimation of soil pressures.
