A footing's overall settling in clay is thought to be made up of the following elements.
According to Skempton and Bjerrum, a footing's overall settlement in clay can be broken down into three parts, S = Si + Sc + Ss.
A negative projecting conduit has a settlement ratio of .
Since the crucial plane settles more than the natural ground, the settlement ratio for negative projecting conduits is always negative.
At __________, Rankine considered element 1 to be the initial soil component.
Rankine thought about the balance of two soil components, the first one being immediately beneath the foundation (element 1).
Which of the following purposes frequently calls for the use of earth embankments or slopes?
Earth embankments are frequently needed for construction of roads, railways, levees, earth dams, and river training projects.
The types of positive projecting conduits are .
There are four different kinds of positive projecting conduits: (1) complete ditch conditions (2) complete projection conduits iii) a ditch conduit that isn't finished, and iv) unfinished projection conduits.
Cohesion-free soil has a surface bearing capacity of .
The bearing capacity of cohesion-less soil is zero at the ground surface, according to Rankine's equation.
Calculating the immediate settlement using the expression based on
The following expression, based on the principle of elasticity, can be used to calculate the instantaneous settlement: Si = q B (1-2/E s) I w.
Which of the following represents a slope that never ends?
In nature, there are no infinitely steep slopes.
A structure's gross pressure intensity (q) is .
The entire pressure at the footing caused by the weight of the superstructure is known as the gross pressure intensity, or q.
Another name for the safe bearing capacity is .
The ultimate bearing capacity qf divided by a safety factor F is another name for the safe bearing capacity.
The various sorts of slopes are classified.
There are two different kinds of slopes: infinite slopes and finite slopes.
Location of critical plane in conduit:
The critical plane is tangential to the top of the conduit and is horizontal in nature.
Slope failure could be brought on by .
The gravitational force that tends to pull the upper portions of the soil mass downward to a substantially more level surface is the primary cause of slope collapse.
Which of the following is referenced by the component Sc, which is employed in the overall settlement of clay?
The following list includes the three elements that clay settlement requires:
Sc = consolidation settlement
Si = immediate elastic settlement
Ss = settlement due to secondary consolidation of clay.
The _________ determines the relative movements' magnitude and direction between the conduits' internal and external prisms.
The settlement ratio, denoted by the formula rsd = (sm + sg) - (sf + dc)/sm, determines the size and direction of relative movements.
Rigid square footing's influencing component is .
BIS Code IS: 8009 Part 1 of 1976 states that the influence factor Iw for stiff footing should be 0.82.
