1. A 200 cm borehole log of a limestone is shown in Figure. Find the RQD and the core recovery ratio. Classify the limestone according to RQD classification. Core run total length - 200 cm No Recovery recovery 5.25 cm 43 cm 18 cm 18 cm 29.5 cm 37.5 cm Mechanical break caused by drilling No pieces > 10 cm 2. A rock core of limestone is 3 in. in diameter and 6 in. long is loaded to failure in an confined compression testing machine. If the failure load P was 60,150 lb, what is the unconfined compression strength (UCS) o of the limestone sample? Calculate the UCS in psi, kPa, and MPa. Classify the rock according to Deere & Miller, 1966

2. Sand at a given relative density has a friction angle of approximately 33° (relatively low stress). When the sample is unsaturated at a given value of saturation (not given to you), the specimen has a negative pore pressure of 5 kPa. How tall a sandcastle "vertical" wall can you construct? What would happen to your sandcastle if the level of saturation suddenly increased? (Assume a total unit weight of 18 kN/m³)

A parameter m in the Hoek-Brown criterion indicates how the type of rock affects the criterion's strength. It is anticipated that the rock will be stronger with a greater value of m. Using the values of m provided in the question and comparing the peak compressive strengths of granite, rhyolite, and marble with each other, qu = 100MPa For marble (m = 7): peak compressive strength =? For rhyolite (m =17): peak compressive strength =? For granite (m = 25): peak compressive strength =?

A crushed rock has a Gs = 2.68. In the loose state the porosity is 46% and when the porosity compacted is 20%. Compute the ratio of compacted volume to loose volume.
Steel plates with mass of 1500 g each were stacked on topof a 75 mm diameter and 150 mm high clay specimen,as shown in Figure P2.22 (attached). If the undrained shear strengthof the specimen is 45.0 kN/m2, how many plates can bestacked before the specimen fails? What is the consistencyterm for this clay?
