Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.

In the soil illustrated in the picture below, a 60-foot-long drilled pile is to be built using the open hole method. The pile will be 24 inches in diameter, and the bottom will be 60 inches in diameter. The soil conditions are homogeneous. Determine the allowable downward load capacity using a method. (The soil is in dry condition) (All the measurements are in feet) -1.5 Stiff silty clay Y = 105 lb/ft3 Su = 1600 lb/ft² Stiff silty clay Y = 108 lb/ft³ Su 1400 lb/ft² T Very Stiff silty clay y = 109 lb/ft³ Su = 4000 lb/ft² 12 25 23
7. If a 45 cm diameter pipe pile is driven into clayey soil to a depth of 12 m. (a) what would the allowable load capacity (Q) be? The water table is 2 m below the ground surface and the soil profile consists of two clay layers (refer to the figure below). Use the ß method to calculate skin friction and the R=30° for all clay layers. (b) Explain how you selected FS value you use. 12 m ▶ 9m 2m 45 cm Y = 18.5kN/m³ = 30kN/m² Ysat = 19kN/m³ C₂ = 30kN/m² Ysat = 20kN/m² S = 60kN/m²
An excavation is rapidly made on site as depicted in the Figure below. The soil wedge above the critical slip surface is divided into thirteen slices. Based on the ordinary method of slices, calculate the ratio (R/S) between the Resisting Force (R) and the Driving Force (S) for slice #3, shortly after the excavation is completed. (Acceptable tolerance = 4%). The geometry of slice #3 and the soil properties are provided in the tables below. The height of water at the middle of the slice is hw = 3.0 m. Note that the total weight of the slice is equal to the weight of the saturated soil below the water table plus the weight of the moist soil above the water table. Hint: the weight of slice #3 is 495 kN
7. A 12m long concrete pile with diameter = 0.45m is drilled into normally consolidated clay with S, = 90 kPa and friction angle = 32 degrees. The pile is loaded with 300 kN and in response to such loading, it settles 2.5mm. What is the mobilized short term end bearing resistance? Show your work and circle your answer.
