rResult:- The primary settlement of OC clay having thickness 4m is (Se)= 30.25 cm approximately;
The co-efficient of consolidation of a clay(Cv)= 3.392 (m^2)/year
Question 2 [Marks: 15 +10=25] 200kPa of construction stress was applied on top of the soil...
help with problems 1 & 2 please and explain Problem 1 A deposit of Swedish clay is 15 m thick drained at both top and bottom. The coefficient of consolidation for the clay layer was estimated to be 1 x 10 cm/sec from laboratory test. The ultimate consolidation settlement (Sc) was calculated under the applied load in the field and was found 80 cm. Find the following: a) How long would it take for settlement of 40 cm and 70...
Please, show step by step and clearly. problem 9.17, (Use 3 equally divided sub-layers for the 15 m clay layer). thanks please, resolve question 9.17 (Use 3 equally divided sub-layers for the 15 m clay layer) 9.16 The soil profile and the loading condition are given in the followin n) figure. Total new footing stress including the foundation at z 2 is 400 kN/m2. The soil profile has a rather thick clay layer (15 so that the layer should be...
in part b, how is h=4 l = 10 b=8 and d=4 ?? Question Nine: For the flexible loaded area (5 mx 7 m) shown below.calculate: (a) The average consolidation settlement beneath the footing given that the load spreads evenly through the clay at a 2:1 ratio. For your calculations, divide the appropriate layer into two equal sub-layers. (b) The average immediate settlement beneath the footing given that the load spreads evenly through the day at a 2:1 ratio. 4800...
Please assist with Geotechnical engineering Question 3 (70) Design an isolated rectangular footing of dimension 4m x 5m. The gross pressure acting at the base of the footing is 150 kN/m2. Choose the depth of foundation such that the factor of safety is exactly 3 against shear failure. Also check against the permissible settlement (75mm) to ensure that the design is safe from the settlement criterion too. If the design is not safe against settlement criterion, then choose the proper...
Q1 (10 marks) You have been asked to examine the bearing capacity of several different rectangular pad footings. The width of each of the footings is to remain constant wil vary. In order to reduce the number of calculations, you have decided to plot the ultimate bearing capacity against the length of the footing. The properties of the underlying soil profile are given in Table 1.1. The base of the footing is to be located 1 m below ground level...
10. A proposed attice building will include an 8.1 bin square, 3-ft deep spread ating that will support a vertical downward service load of 160 k The soil below this footing is an overconsolidated clay (OC case with the following engineering properties Cell + ) = 0 10. C I + )-0022, and y = 113 ih This soil strata extends to a great depth and the groundwater table is at a depth of 50 It below the ground surface...
