Question 58
Open questionCE-2NAT2 marksNeeds review
A square footing is to be designed to carry a column load of 500 kN which is resting on a soil stratum having the following average properties: bulk unit weight = 19 kN/m
; angle of internal friction = 0° and cohesion = 25 kPa. Considering the depth of the footing as 1 m and adopting Meyerhof’s bearing capacity theory with a factor of safety of 3, the width of the footing (in m) is __________________ (round off to one decimal place)[Assume the applicable shape and depth factor values as unity; ground water level at greater depth.]

For the flow setup shown in the figure (not to scale), the hydraulic conductivities of the two soil samples, Soil 1 and Soil 2, are 10 m/s and 1 mm/s, respectively. Assume the unit weight of water as 10 kN/m
and ignore the velocity head. At steady state, what is the total head (in m, rounded off to two decimal places) at any point located at the junction of the two samples? __________________________
