The ratio between the volumes of voids to the volume of solids of a soil mass

(a)  

The ratio of the volume of water to the volume of voids

(a)  

It is a term used to describe the degree of firmness of a soil

(a)  

With the continuous loss of moisture, it is a stage of wherein the equilibrium is reached that causes more loss of moisture that will result in no further volume change.

(a)  

It has an intensity of q(kN/m) acts on the surface of a soil mass.

(a)  

A type of soil wherein the most of the soil grains are the same size

(a)  

It is the ratio between the volumes of voids to the total volume of a soil mass

(a)  

It classifies the two broad categories of soils; the coarse grained soils and fine-grained soils. (dont use acronym)

(a)  

A type of soil that is characterized by two or more humps in the grading curve.

(a)  

Caused by plastic adjustment of soil fabrics. It is an additional form of compression that occurs at constant effective stress.

(a)  

Hydraulic gradient that brings a soil mass to static liquefaction

(a)  

The soil is classified into seven major groups: A-1 through A-7.

(a)  

The state of compactness of a natural granular soil

(a)  

It consist of shaking the soil sample through a set of sieves that have progressively smaller openings.

(a)  

The sum of the effective stress and neutral stress

(a)  

Defines the relative consistency of a cohesive soil in the natural state

(a)  

Is in essence a gravity wall that has been given a wider base (a toe or heel or both) to increase its stability.

(a)  

Usually built of plain concrete

(a)  

In this classification system, the soils are named after their principal components, such as sandy clay, silty clay, silty loam and so on.

(a)  

The stress induced by water-pressures

(a)  

Defined as a structure whose primary purpose is to prevent lateral movement of earth or some other material

(a)  

A liquid above the level of zero pressure due to a net upward force produced by the attraction of the water molecules to a solid surface

(a)  

It caused by elastic deformation of dry, moist, and saturated soils, without any change in moisture content.

(a)  

caused by a volume change in saturated cohesive soils due to expulsion of water that occupies the void spaces.

(a)  

time for 90% consolidation

(a)  

This parameter is the diameter in the curve corresponding to 10% finer.

(a)  

A type of soil is which the particle sizes are distributed over a wide range.

(a)  

time for 50% consolidation

(a)  

It occurs directly after application of a load, without change in moisture content.

(a)  

The stress resulting from particle-to-particle contact of soil

(a)  

A material fails because of a critical combination of normal stress and shearing stress, and not from either maximum normal or shear stress alone.

(a)  

Simplest form of a shear test

(a)  

The ratio between the lateral and vertical principal effective stresses when an earth retaining structure moves away from a retained soil.

(a)  

A depth below the ground surface where the base of the foundation rests

(a)  

The ratio between the lateral and vertical principal effective stresses when an earth retaining structure forced against from a retained soil.

(a)  

If a retaining structure does not move either to the right or to the left of its initial position, the soil mass will be in a state of elastic equilibrium, meaning the horizontal strain is zero,

(a)  

the maximum pressure that the soil can support

(a)  

The working pressure that would ensure a margin of safety against collapse of the structure from shear failure

(a)  

a condition where there is relatively high compression of the soil underlying the footing with neither heaving at the ground surface nor tilting of the foundation.

(a)  

Most common cantilever wall

(a)  

a condition where significant compression of the soil occurs but only slight heave occurs at the ground surface

(a)  

The ratio of the ultimate net bearing capacity to allowable bearing capacity or to the applied maximum vertical stress.

(a)  

Frequently used when property line restrictions forbid the use of a t-shaped wall.

(a)  

Consist of three main components: base, stem and intermittent vertical ribes.

(a)  

Constructed by placing the ribs on the front face of the stem where they act in compression

(a)  

Generally short and typically accompanied by wing walls

(a)  

The structural elements of the wall should be so proportioned

(a)  

it is the part of structure which transmits the building directly into the underlying soil.

(a)  

A foundation consisting of a small slab for transmitting the structure load to the underlying soil.

(a)  

One in which the ration of the embedment depth to the minimum plan dimension, which is usually the width, is Df/B <= 2.5

(a)  

the maximum pressure that the soil can support above its current overburden pressure

(a)  

the pressure of the soil removed to place the footing

(a)  

continuous failure surface develops between the edge of the footy and the ground surface

(a)
