Expert Solution & Answer
Check Mark

Explanation of Solution

  • The ellipsoid is defined in mathematical terms as something which has been used to compute the positions of widely spaced points which are located through the control surveys.

Sizes and shapes of the ellipsoids can be defined by two parameters. The lists of parameters of two ellipsoids are Clarke 1866. Ellipsoids of the defining parameters will be semi axes a and b . There are also parameters GRS80 and WGS84 ; the defining parameters will be semi major axis a and the flattening factor f .

Q2/ A (2m x 4 m) rectangular flexible foundation is placed above the ground surface (G.S) for two layers of clay, each layer 10 m thick. The modulus of Elasticity (E.) of the upper layer is 13 MN/m² and that of the lower layer is 15 MN/m². The Poisson ratio is (u, = 0.6) for the two layers. The pressure (stress) of 100 kN/m²is distributed along the surface of foundation. Determine the rigid immediate settlement at the corner of the foundation using Elastic theory method?
Q1/ Find the maximum allowable load for a square foundation (3 m x 3 m) placed vertically in cohesive soil? (Use Terzaghi equation) Note: Yt=Yeat=18 kN/m³ Depth of foundation = 1.5 m Depth of water table below the ground surface = 0.8 m Factor of safety 3 C=20 Yw = 10 kN/m³ = No vertical or inclined loads
