Geomechanics 2 Civl 462 Tutorial Sheet - 5 1. A reinforced concrete foundation of dimensions 20 m X 40 m exerts a uniform pressure of 200kPa on a semi infinite saturated soil (E=50 MPa). Determine the value of immediate settlement under the foundation. (assume µ=0.5). 2. The plan of a proposed soil heap is shown in Fig.1. The tip will be about 23 m high and will sit on a thick, soft alluvial deposit (E=15MPa). It is estimated that the eventual uniform bearing pressure on the soil will be about 300 kPa.

Unformatted text preview: Estimate the immediate settlement under point A at the surface of the soil. (assume µ=0.5). 3. It is proposed to construct a reinforced concrete foundation, length 30 m and width 10 m on the top of the layer of clay of thickness 20 m which is having a saturated unit weight of 18.5kN/m3. The uniform foundation pressure = 200kPa. Determine the total settlement at the centre of the foundation (Assume E= 32.5 MPa; µ=0.5; m v = 7.6x10-5 m 2 /kN) 50 m 80 m 150 m 50 m A...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
