Engineering Geology And Geotechnics - Lecture 4

[@scorchgardenultrahothotsau7919]

I'm not an engineer, I'm not even a contractor. I make hot sauces. But as an entrepreneur listening to these lectures this man is giving golden advice as far as how to run a business. Thank you so much sir for this.

Loving this series. All because of Nick Zentner, an awesome Geology teacher at Central Washington university who live streams about the Pacific northwest.

[@Lanse1984]

I love Nick also.

May I "assume" the first drawing shown was a Geologic Block Diagram? I ask because I am Brand New here. Are Geologic Block Diagrams only good for giving a General idea for Non-Specific Site's Geology BUT NOT for a Specific Site's Geology? May I "assume" this is especially True for important Geotechnical decisions being made off of Block Diagrams? Would Trench Observations, when possible (such as being shallow enough OR no excessive damage to the surface) be preferred over Geophysical Methods -OR- should Geophysical Investigations "always" be considered the First Choice when cost is NOT a concern?

This professor is a stud.

i cant stress how intelligent this guy is , i loved the wood chips idea

[@geezerdombroadcast]

+oussama Ali Damned under achiever, : (. He makes me feel like a slug subhuman. Makes you wonder if people aren't divided into real humans, and decoys. Pretty smart, pretty tough, relentless machine. I have worked for a few people a lot like him. I wish I was more disciplined as a child, when I think of him. Made of special stuff, (piss, and vinegar)!

[@oussamaali8393]

Peter Mullen ROFL , yea basically he is THE engineer and we are just bunch of technicians . I've sent him a message to thank him for these wonderful lectures

[@djblackprincecdn]

I wish I had known more about this before being a materials tester on a clay subgrade highway in Northern Alberta. Could have prevented so much future frost heave. I hope that highway is doing well all these years later (its not, its Northern Alberta).

What I like about this lecture is that it's not just theory, even though it's important to understand soil mechanics theory. This lecture take the approach, "Here's the problem, and here are some solutions." That's VERY useful for students.

Any idiot can design a structure but not everyone can design a foundation.This is what my professor said some 34 years ago which is very true indeed.

How can you talk about Poisson ratio for water? Maybe Poisson ratio has a different definition in soil mechanics, but the traditional definition of Poisson ratio is transverse strain/axial strain for a solid sample that is in tension or compression. Water is a liquid and can resist no tension or compression unless it is constrained. And water is only incompressible as an engineering assumption for relatively low pressures. If you raise the pressure high enough, density increases.

[@Martin-iw1ll]

I think it was to do with Elasticity theory where you only need two modulus to derive the other moduluses. By assuming water is incompressible (which okay for the pressures we are dealing with in soil mechanics), that means the bulk modulus is infinity, then as bulk modulus K=E/[3(1-2v)], then v must be 0.5 or close to that value

yo chill hahaha

[@brucewinningham4959]

Can someone please tell me "what is the difference(s) between water running downhill versus water running down gradient?

[@EricMcD15]

The gradient refers to the gradient of the groundwater table, which is underground, under the hill

[@brucewinningham4959]

@@EricMcD15 -- OK, I think I have got it. THANK YOU.

27:00 so where do I find those military geology classes?

[@CivilThinking]

Have many channels out there..

[@billwiggy]

On his website

[@ParanoidAndroid9]

I am sorry I have not been around. If you would not mind giving me a week or two, I will be back in the classroom!

[@marijuskunickas9315]

does anyone know what kind of program they use for designs?

That girls backhanded question about the SUBTERRANEAN drain was rude. ‘I can’t image the homeowners being too happy with the way that that looks so how long does that stay there?’ - 🤦🏼‍♀️ ummm what does she think ‘subterranean’ means? Lady, it’s an underground drain - so if something is ‘underground’, that means there must be ground above it. So OBVIOUSLY it’s going to be covered over after he’s done putting it in…. You think he just left it open like that?! Lol What a totally unnecessary passive aggressive question.

I know of a missing link in the education of geologists. They tell us that our planet Earth has the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters that separate the eras from the world. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its chronology and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
