Example3.1 For a square foundation \( 2 \mathrm{~m} * 2 \mathrm{~m} \) in plan, the soil supporting the foundation has a friction angle of \( \phi=25 \) and \( c=20 \mathrm{kN} / \mathrm{m}^{3} \). the unit weight of soil, \( \gamma \), is \( 16.5 \mathrm{kN} / \mathrm{m}^{3} \). Determine the allowable gross load on the foundation with a factor of safety of 3. assume the depth of the foundation is \( 1.5 \mathrm{~m} \) and the general shear failure occurs in the soil. Re do the above problem using meryhofs method.

Step 1
The area of the foundation, A, is given by the formula A = length * width. In this case, the length and width of the foundation are both 2m, so A = 2m * 2m = 4m^2. Show more…

For the basement of a new house, a hole is dug in the ground, with vertical sides going down $2.40 \mathrm{m} .$ A concrete foundation wall is built across the 9.60 -m width of the excavation. This foundation wall is 0.183 $\mathrm{m}$ from the front of the basement hole. During a rainstorm, drainage from the street fills up the space in front of the concrete wall, but not the basement behind the wall. The water does not soak into the clay soil. Find the force the water causes on the foundation wall. For comparison, the gravitational force exerted on the water is $(2.40 \mathrm{m})(9.60 \mathrm{m})(0.183 \mathrm{m})\left(1000 \mathrm{kg} / \mathrm{m}^{3}\right)\left(9.80 \mathrm{m} / \mathrm{s}^{2}\right)=$ $41.3 \mathrm{kN} .$
Determine the maximum allowable load $\mathbf{P}$ that can be safely supported by the frame if $t=1.25$ in. and $b=3.5$ in. The wood has a normal failure stress of $\sigma_{\text {fail }}=6 \mathrm{ksi},$ and a shear failure stress of $\tau_{\text {fail }}=1.5$ ksi. Use a factor of safety against failure of 2
The Keswick dam in Problem 2.94 is made of concrete and has a specific weight of $150 \mathrm{lb} / \mathrm{ft}^{3}$. The hydrostatic forces and the weight of the dam produce a total vertical force of the dam on the foundation. Find the magnitude and location of this total vertical force. Consider a unit length of the $\operatorname{dam}(b=1 \mathrm{ft})$.
