Question #$4$: Determine the maximum pressure at the base of a $4m$ high temporary shoring wall as

shown below. The soil behind the wall is cohesionless soil with the properties shown below. The water

table is located $2m$ below the ground surface. Assume water pressure acts on this shoring wall. A

surcharge of $12$kPa is placed adjacent to the wall.

Utilize formula:

p$=$k$(\backslash$gamma $($H$-$hw$)+\backslash$gamma $\text{'}$hw$+$q$)+\backslash$gamma w$*$hw

Soil A:

$Y_T=19\mathrm{.}0k\frac{N}{m^3}$

$Y_{\text{S}\text{A}\text{T}}=19\mathrm{.}8k\frac{N}{m^3}$

$=30$
