May influence what to be built and affect the design and construction

used to retrieve sample of rocks

checking the behavior of soil below ground level

the property of soil that makes the water pass through

Sampling:

used to reach desired depth

Larger than boreholes

3 methods of Boring

cylindrical sample of rocks

protective structure to prevent collapsing of walls

driven to soil in order to collect undisturbed soil samples.

drilling or advancing a hole in the ground

prevents in the collapsing of hole walls

Where soil samples go

maximum depth of hand operated auger

3 methods or Types of Testing

determine the shear strength of soft clays

with porous element

-determining the soil type. - same with SPT but different sampler called "Cone Penetrometer"

Affects construction:

Layers of rocks

natural structure get disturbed during the sampling process of soil

procedure of determining surface and subsurface conditions of an area of proposed construction

Soil Exploration:

a screw-like tool used to dig a hole on the ground

Twice the least dimension+ depth of ______.

horizontal movement of water through soil

a hole in the ground

Apex Angle is 60°

-to determine the relative density of granular soil. -no bonding forces

determining the characteristics or properties of the soil

2 types of machine operated auger

Element to measure pore pressure

It says the "Depth at least 5m hard strata until a suitable bearing layer is reached."

Retain their natural structure and water content during the sampling process of soil.

soil profile

maximum depth of test pits

Have a diamond tip

removing soil from the hole
