Problem 1A 3m x 3m square footing is constructed at a depth of 2m in a 26m deep clay layer with following soil properties: g =16.5kN/m3, Normally Consolidated Clay, eo= 0.65, Cc = 0.25,ms=5 and Es= 6.0 MN/m2. If there is a 1000kN structural load on the footing, calculate the consolidation settlement of the footing.A 2m X 2m footing carrying 1400kN load is constructed in a site with 2.5m thick clay layer under a 2.5m thick sand layer. If the footing and the ground water table are located at 1.5m below the surface, calculate the consolidation settlement of the footing. You may assume the following soil properties: for sand gsat = 19.25kN/m3 and gt = 7kN/m3, and for clay eo= 0.65, Cc = 0.25, Cs = 0.06, s’p = 200kN/m2 and gsat =19.25kN/m3.A 1882kN load is carried by a 2.6m x 2.6m square footing at a depth of 1.4m in a 30 m deep sand layer. Given the following soil properties for soil calculate the total settlement of the footing after 10 years. Where soil properties are: g = 15.9 kN/m3, ms=0.5 and Es= 30.0 MN/m2.

Problem 1

A 3m x 3m square footing is constructed at a depth of 2m in a 26m deep clay layer with following soil properties: g =16.5kN/m³, Normally Consolidated Clay, e_o= 0.65, Cc = 0.25,ms=5 and Es= 6.0 MN/m2. If there is a 1000kN structural load on the footing, calculate the consolidation settlement of the footing.
A 2m X 2m footing carrying 1400kN load is constructed in a site with 2.5m thick clay layer under a 2.5m thick sand layer. If the footing and the ground water table are located at 1.5m below the surface, calculate the consolidation settlement of the footing. You may assume the following soil properties: for sand gsat = 19.25kN/m³ and gt = 7kN/m³, and for clay eo= 0.65, Cc = 0.25, Cs = 0.06, s’p = 200kN/m² and gsat =19.25kN/m³.
A 1882kN load is carried by a 2.6m x 2.6m square footing at a depth of 1.4m in a 30 m deep sand layer. Given the following soil properties for soil calculate the total settlement of the footing after 10 years. Where soil properties are: g = 15.9 kN/m³, ms=0.5 and Es= 30.0 MN/m².
