All that work, and then in 1978 another slide closed highway 39 near there and it's been closed ever since. But at least now I'm tempted to hike a bit on it and find this section and see how it's doing after all this time and if it's held up.

Since this was basically something new and untried before in North America my best guess is there was a whole lot more instrumentation added during the construction phase so data could be gathered for use on other projects. It would be interesting to know if that wall is still there and how well it's stood up in the last 60 or so years. My other guess is because of changes in methods and costs a concrete bridge to do the same might now be more cost effective. For the 1960's those were pretty high costs per ton of compacted earth. Open cabs and no ROPS on the equipment make it look pretty strange today. Glad I missed that.

If I could handle the cold I would move there myself

I have no idea what im watching but this is interesting

Damn, that's some deep-archive stuff, love it! :D

Excellent work very good video thanks

pretty cool we do it so much different now!

i'd describe this as a fail. twenty years ago i was involved in a similar technique to prevent pressure on a tilt-up preformed concrete wall to maximise the size of a car park on a sloping site. maximum height of about 12'. it involved polypropylene mesh fabric laid down where this method used flat steel bar, towards the edge, then built up a bit over 18'' then the sheeting was folded back and another sheet was laid down and again folded on top of another 18" of dirt. the smart arse engineer who thought this bull shit up demanded we didn't compact near the edges. the concrete wall had sagged off vertical, especially near the corner, about 6 months later. there was also some pinning with cables involved. there are fundamentals about retaining walls. 5-10% slope is needed or extra thick concrete at the base on the inside face that tapers to the top to make up the 5-10%. and deep stable footings below ground at the base. liquefaction caused by earthquakes or even heavy trucks will destroy this method shown. steel reinforced concrete has already been invented. it works great. this method is like sandbags. good for a foot or so. it should be compulsory for all engineers and architects to learn how to dig a hole with a shovel as part of their training before they get a qualification. fascinating earthmoving machinery. thank you for posting.

engineer-fancy word for over paid jackass. this applies mainly to inspectors though- a clown that couldn't hack it as a contractor but thinks he can tell one what's wrong and right!!!!!!!!

Yea.....I dont now what this is...but its interestin.... Is wrangler cool jeans 👖..?

This clip is the perfect cure for insomnia

Interesting!!!...

That's it. And that's how I met your grandmother!!!

These are my favorite jobs

I never knew it was so mathmatically involved.

It's no wonder California had financial difficulties. they were spending big bucks doing a study that was already known for centuries before. I've done retaining walls and know that you have to stair step it up from the bottom or it will eventual come down. I wonder how long it was before this came down because it wasn't done to prevent additional slides, only to prevent the current one from moving again.

You missed the entire point, this wasn't about the retaining wall, but about how not to put too much stress on the unstable ground. A vehicle going over the road puts pressure on the ground, that pressure is distributed on several layers of horizontal slats connected to the retaining wall, the pressure on the slats tugs on the wall. That means when a vehicle is going over it, the weight of the vehicle pulls the wall inwards towards the road. The point of the exercise is to redistribute a heavy but random local force over a much larger area, making that part of the road less susceptible to failure.

how did I get here?

Can you authorize your work to me? I need to translate your work.

It's now 46 years later...I'm curious how it's holding up.

Oh it was? Sorry I wasnt really bothered watching the full 31 minutes of it to find out for myself. Thanks anyways though.

🙏🙏🙏🙏🙏

the earth & rock slide would be blamed on climate change if it happened today..

Good 👍

oh awesome i am the 1th and only 1rd . yes i am 1nd. oh and thanx for the upload too !

what a waste of taxpayers money if it holds just ~ 30 years Blasting and building on stone would have likeley been cheaper Still a good video thanks for uploding

Is this Donald duck narrating this?

all this becuase we ran out of mammoths to eat.

I am sorry but, this is a waste of materiel and has no compensation effect on the concrete, asphalt is cheaper and has the compensation effect from itself ! 0o0

get a gps tracker

Doesn't work. California highways are still sliding down the hills to this day. Waste of tax money to keep rebuilding them. Engineers think they are so smart.
