Calculate: a) effective stresses at points A and B before the placement of foundations 1 and 2, b)the increase of pressure at point A as a result of the placement of the circular foundation 1, c) theincrease of pressure at point B as a result of the placement of the strip foundation 2.
Consider the total head-loss in the system forthis flow is 18.56 ft (head-losses in first and second pipe are 13.83 ft and 4.73 ftrespectively). Please show numerical values for EGL/HGL at the beginning/end/intermediatechange point. (Point distribution: elevation determination 5 points, EGL, HGL lines 4points)

(a) Estimate the immediate settlement beneath the center of the
footing. Assuming that Poisson's ratios of sand and soft clay are
0.3 and 0.5, respectively. Use numerical integration approach.
For the calculations, use layers (below the bottom of the footing)
of thicknesses: 1 m; 1.5 m, and 2.5 m.
(b) Determine the primary consolidation settlement beneath the
center of the footing.
(c) Redo Part (b) if OCR=1.1.
Note: Use the 2:1 method to determine the stress increase below
the footing. For parts (b) and (c), use the one-dimensional
consolidation theory.
