Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.

An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a borrow pit is 15% and its void ratio is 0.69. The swell index is 1.2. The specification requires the embankment to be compacted to a dry unit weight of 18kN/m^3. Determine, for a 1-km length of embankment, the following;(d) Volume of the borrow pit material required considering swell. (e) The number of truckloads of sandy soil required for the construction. The full capacity of each truck is 22.2m3, and local government regulations require a maximum capacity of 90%. (f) The weight of dry soil in one truckload.

A cut is made into a homogeneous soil as depicted in the figure below, at an angle of 60° with the horizontal. Calculate the resisting shear force in kN along the failure plane given that the shear force applied by the overlying soil wedge is 120 kN. The failure plane is at an angle of 40° from the horizontal direction and the ground water level is below this plane. Assume drained conditions for this question.
