I'm not an engineer but I took my fair share of engineering and physics classes in high school and college. Now I just binge KZread videos and make stuff. Your video was probably recommended because I've watched a ton of Practical Engineering's videos. Your simple explanation helped me understand why the retaining wall behind my house failed more clearly than any other resource I've looked at and I'll be able to make more informed choices when we replace it. Thanks!

Thank you so much Track (favorite comment so far, and yes I read them all😅). At some point there will be a part 2 to this video with more practical explanations about installation and drainage (possibly a bit more math/physics as well). You wouldn't believe how many failed walls I see around that (possibly) could have been avoided. I would say proper drainage and compacted good-quality backfill would have avoided more than 75% of the failures. (disclaimer these are gut feeling guesses, not based on adequate studies)

Hello, geotechnical engineer here. Can you please keep making these types of videos. This one was really useful for the younger staff. Thanks.

Great Geotechnical series so far. Would love to see more

As a contractor here in pa, 4 things I find that contribute to retaining wall failures, drainage, frost jacking, poor backfill stock, wall material …chiefly using soils that are poor in draining, lack of aggregate to aid in drainage, and clay soils that could be useful if utilized properly…frost typically enters a design from its face and from the top, both have forcing action, and once that is set it cannot be removed, the wall usually suffers from displacement(s), rotation, or detachment…..wall design or selection of materials for the wall itself…

This presentation just touches the surface of a great topic. I want more! numbers even! geek out! 😎

You are correct Rai, there is so much more. We didn't talk much about cohesive soils and the undrained condition. Most likely there will be a follow up video to this but possibly after we go over foundations and slopes first.

Same. I really like the style you cover this material, and would love even more depth.

As a geotechnical engineer who designs retaining walls, I found this video to be both well explained and accurate. May even share with the folks at the office...

I'm a civil engineer, but have primarily been working in aviation. This is a great refresher and a much more intuitive way of visualizing things than many of the ways I was taught, well done!

Thank you very much for your excellent work. You make it easy to approach topics. You make problems visual and much more intuitive. In this case, you address an important subject for the general learning and mastery of civil engineering. I appreciate your work, as professional with 30 years of civil engineering on my backs, specialized in hydraulics, and working in civil works management in general, in Municipal Public Administration. I come to here because I appreciate the continuous study (throughout my life) of all kinds of topics globally related to my profession, such as calculus, materials, physics, chemistry and mathematics, about all specialties, including programming. And here I am, reflecting on soil mechanics, recording Prof. Manuel de Matos Fernandes, in the 80's of last century, at my Alma Mater, FEUP, Porto, Portugal.

As an architect I can't thank you enough for your content.

Would love to see a drainage follow up. I’m a career carpenter and am fascinated how soils tests barely existed when I started and are now first order of pre-construction. For very good reasons.

This is incredibly helpful to easily understand the mechanics and concept of geotechnical engineering. I hope there will be more of this! Thank you

This was very helpful. A dry stone wall has natural drainage, but this video made clear to me the value of compacted backfill. I am very grateful.

Very well presented. I’m a geotechnical engineer in Florida. I don’t see retaining wall failures often here. One that sticks out in my memory is a set of walls in a neighborhood that had trouble due to drainage problems. The poor drainage caused seepage and piping of the soils below the wall foundations. The loss of support to the foundations led to partial collapse of at least one of the walls. I don’t know too many details because it wasn’t one of my projects. It was in a neighborhood next to one of my projects, and I heard about it from the city engineer.

just mind blowing! Please keep making videos like these and we'll definitely like part-2 of this video.

Looking forward to a “Part 2” of this video

I’m considering to do some alterations in my garden which involve shifting a retaining wall back by a meter or so, and to also place it against my single brick layer garage wall, but have no knowledge of what makes a retaining wall to be strong, so this video is a useful starter. I’ll dig out your first video as you suggest, and have a browse around your channel to increase my knowledge of this topic. Thanks for the video! P.S. I’m not sure if my plan is even a good idea as I don’t want my garage wall to collapse(!), so will also seek professional help if I decide to proceed

Very interesting. We have some failing retaining wall around where I live.

Thank you for visualizing this complex Geotechnical concepts. Stability of soil is arguably the greatest challenge. In addition, one can intuitively summarise the four scenarios as follows: Case 1: compaction increases the shear strength of particles as they're pushed hard against another. For instance, if you press your knucles against each other and try sliding your fists, if you press hard as you do so there is increased resistance. Hence a relatively higher factor of safety (FS) is expected. Case 2: in addition to the already compacted soil, additional strength is added by the reinforcement. Therefore it makes sense that FS2 > FS1 Case 3: The key component here, is the presence of pore water pressure (pwp), simply put the presence of water decreases the shear strength of soil. This is because pwp refers to water within the soil voids which pushes against the grains, hence alluding to the fist-knucle anology, we can see why that is the case. In comparison to the two cases, we expect FS2>FS1>FS3. Case 4: Loose soil generally has higher shear strength than wet soil but lower than compacted soil, thus, we can deduce: FS2 >FS1 >FS3 >FS4 Thank you for these informative series, would absolutely love to see more visualizations, and other concepts such as 2D seepage.

I have a question. I'm adding a low footer bed to a front drive that will only be about 18-24 inches. how high do I need to start worrying about pressure of the soil against the low wall. I'll be using cement breeze blocks and the bottom half of the bed will be type 1 rubble. with standard soil on top. I need it to withstand someone standing on it. I was going to use standard cement to adhere the blocks together and was thinking of putting steel rods into the concrete floor that is the driveway at present. thank you.

I'm a concrete superintendent and we always compact the soil before laying any concrete slab and the same should apply to elevated soil, specially if behind a retaining wall , I'd build that wall thick like a Cantilever on the bottom to avoid tipping over and water drainage system like mentioned in the video

I do would like a second part of this video . Thanks first of all .
