A Vertical Cut 4 4 M High Is Excavated In Saturated Intact Clay The Clay Is Isotropic And Has An Undrained Shear Streng 1 (62.08 KiB) Viewed 12 times

A vertical cut 4.4 m high is excavated in saturated intact clay. The clay is isotropic and has an undrained shear strength of 37.4 kN/m² and a saturated unit weight of 17 kN/m³. Assume that a vertical, air-filled tension crack forms behind the cut at a certain (unspecified) distance to its crest, with a depth of 1.04 m. For the critical slope angle, determine the factor of safety of the vertical cut, under short-term (end of construction) conditions. Type your answer in three decimal places. Answer: Check What value of this factor of safety will result if the lower part of the cut is then submerged by fresh water to a depth of 1.08 m, the tension crack remaining free of water? Type your answer in three decimal places. Answer: Check
