Soil Liquefaction

"This experiment reproduces the conditions that lead to soil liquefaction. For this reason, a container filled with fine sand and water is placed on a shaking table together with three different metal objects. At the beginning of the experiment, the shear strength of the soil is large enough to sustain the weight of the steel objects without collapsing. However, as the shaking table starts to vibrate, excess pore water pressure is generated causing a reduction in the effective stresses in the soil causing it to fail and resulting in a loss of equilibrium between the soil and the metal objects."

Appreciate the happy cheery music as the houses sink.

Now I need to take a 2-week course to be able to understand this 2-minute video.

Actually scalar energy joins hydrogen and oxygen to make water. The SOLID matter becomes liquid. The liquid was not hiding... ; ) - It was FORMED.

@@sandramilleramplifiedhealt9695 No, this video is showing how shear strength affects construction foundations in soil. While the amount of water in the soil remains mostly unchanged, the flow of that water or some other forces can cause seemingly solid soil to suddenly collapse.

😂😂😂exactly

[@shyamendole1641]

Thanks very helpful for all civil engineering student

[@naiharrison4998]

Big thanks from Hong Kong U!

[@kokoekaykhaing2785]

Thank

[@KawdoruTaon]

It would be better with some speaker telling explanations. But it is visually neat!

[@Siladzy]

Very helpful! Now i know that it’s not some demonic stuff happening

[@firefox5926]

watching from christchurch new zealand :) thankfull it wasnt quite that bad here :P

[@veerchasm1]

Why does physics always involve red farms houses?

[@rahulverma5268]

Study is incomplete without 🤔

[@burlynorth7389]

.....and that folks, is how you bury a civilization like Tartaria.
