eo-0.85, Cc-0.24, cv=18°), over fracture sandstone bedrock. The site is low lying with the water table at the ground surface. (a) What are the vertical total stress, vertical effective stress, and horizontal effective stress at a depth of 5 m below the surface? [3 marks] (b) Development of the site will involve lowering the water table to 1m below the ground surface and the placing of 2m of clean granular fill (ydry = 17 kN/m³), prior to construction at a later date. How much long-term settlement will be induced by the first phase of site development? [2 mark]
