A factory contacted a Geotechnical consultant to design foundation of the tall chimney to take care of flue gases formed during the tiles production. As per design of the Geotechnical Engineer, the chimney should have a square footing of 3.0 m side constructed at a depth of 2.50 m in the sub soil. It was found from the results of the laboratory test on the sample of sub-soil that the shear strength parameters in the form of angle of internal resistance and the cohesion intercept are 36’ and 5 N/m respectively. The moist unit weight is equal to 18.0 kN/m . The chimney is carrying a concentrated load of 5000kN and two horizontal components of load of 200 kN acting at the height of 4.5 m perpendicular to length of the footing and 3.5 m perpendicular to the width of the footing measured from the base of footing.
. Calculate the ultimate bearing capacity of the soil and factor of safety by using the above suggested analysis.

In batching of aggregates the moisture content is expected to be in saturated surface dry condition. However, in a concrete production, the actual moisture content of coarse aggregate on the site just before the batching measured as 8%, and its saturated surface dry condition requires 5% moisture content. If 1000kg/m3 of coarse aggregate and 220kg/m3 of free water is needed for a concrete production, how many kg of coarse aggregate and water is to be placed into the mixer for one m3 of concrete production?

A very wide embankment with height of 3m and the soil unit weight 19 kn/m3 to be constructed. Calculate the normal stress, water pressure and effective stress at two positions: At the middle of clay, the depth = 5 m and the saturated unit weight = 27 kn/m3, and at the middle of sand, the depth = 5 and the saturated unit weight = 21 kn/m3.

For two cases

- Before constructing embankment

-Instantly after constructing the embankment
