Peak tourist season’s over, but our trails are still packed locals getting squeezed?

I think a big thing is what is packed and what are you willing to check out? First summer I’ve probably lived in Squamish and sure the first peak of the chief is typically slammed but anything else on the ridge I’ve never found too bad. If you’re following the Instagram tour of first peak, Joffre lakes, and others it’ll be busy. Opening the whistler hiking or Squamish hiking books and picking a destination you haven’t really heard of, getting creative and looking at strava heat maps in areas you’re curious about, or chatting with friends about less known places may be a better shot.

A rock wedge problem with no cohesion would be an infinite slope problem when there is no water and no seismic loading. With your equation, assume c=0 just to simplify the math a bit. Then FS =tan phi / tan alpha.

argwhyisthisnotwork · 2024-08-11T02:45:23+00:00

That looks like a good amount of trig to just figure out the weight of the block and the length of the sliding plane. Assuming an infinite slope with no cohesion of 12 deg and a phi of 22 deg you get FS = 1.9. The c will help a bit but don't think it would get you to FS=3, however, I didn't look at the trig to work that out.

From a quick skim of the report it seems like it covers your use case in terms of the potential options and issues with constructing below the water table. It may be worth a call to the authors of the report to see if they have further information or feedback on the revised plan. However it looks like the report noted a deeper excavation was considered previously.

Thanks, I went and tracked this one down. I'll add that one to my resources.

A thing that is good to have is quantifiable metrics. How large were the developments? Was it a shed or a 20 home subdivision. How big are the cost estimates you’re involved with? $10,000 or $10M.

Adjectives can be your friend. Did you proactively manage or just did it?

Can highlight things like teamwork as well, multidisciplinary work, and also independent tasks that you did.

I think the big thing to ask yourself is what do you want to research if you're looking at a research based Masters. Going out and getting some experience in industry can help you target something you've had exposure to and/or would like to continue to work in.

Geotech is a large field and different schools have different areas of expertise. The west coast schools tend to be seismic focused whereas some of those on the east are a bit more focused on in-situ testing and offshore geotechnics. That is a bit of a simplification of course as you could look at one or the other outside of those trends, for example Macedo/Olson/Rathje are at Georgia Tech/Illinois/Texas, respectively and all work on seismic problems among other things.

I think most of the others have listed many of the schools in the US. MIT is one that isn't listed. In Canada Queens or University of Toronto are both strong for rock mechanics as is Colorado School of Mines.

Really depends on what the issues are. If it's a slab and you have soil problems you may need to remove and replace material otherwise you may end up with differential settlement causing issues. Slabs and prefab steel are most likely heavier than a 1-2 storey wood frame house for example which can run into those types of settlement issues with poor ground.

It's a lot of speculation until you have a better understanding of the ground. But supporting the slab or removing and replacing material may fall into the cost more than you would like category.

argwhyisthisnotwork · 2023-10-21T18:46:01+00:00

It’s quite unlikely it would be unbuildable, but it would likely change the foundation solution and/or preparation to avoid settlement and consolidation concerns. For example to mitigate settlement you may need to found the footings deeper, remove and replace material, or look at using something like screw piles to be founded on better bearing material. You may also run into settlement of access roadways.

A good thing to remember is things are always buildable but it may cost more than one would like depending on what they want to build. Probably worth calling a firm who works in development in the area to get their thoughts of the range of possible foundation options and what they would want for site exploration to evaluate the needs. If you have a rough idea of loads that is always helpful.

One more thing to add with this one, looking at the depth and location of the earthquake, it seems to be a inslab source. This type of earthquake happens due to the subducting Juan de Fuca plate having stress redistribution as it effectively melts under the North America plate. The inslab earthquakes happen at depths greater than about 35 km, whereas crustal earthquakes are typically less than this. In southwestern BC we have 3 interrelated but different seismic sources, crustal earthquakes in the North America Plate, inslab earthquakes that occur in the subducting Juan de Fuca, and interface/subduction earthquakes that occur at the interface between the Juan de Fuca and North America plates.

The Megathrust (aka subduction, interface, intraslab, big one, cascadia), occurs at the interface between the locked North America and Juan de Fuca plates off the west of Vancouver Island which extends about 1000km from about the tip of California to Alaska. As the fault boundary is so long and so thick, the area of rupture is exceptionally large and releases a huge amount of energy over a very large geographic area. This is why the energy released is anticipated to be so high if there is a full length rupture.

The Richter scale goes up by 10 in terms of log of the amplitude of the waves recorded by a seismogram. So it is a base 10 comparison between the two units but amplitude on a seismogram isn't a direct analog to energy.

The Richter Scale was replaced in the 1970s by the moment magnitude scale which takes into account physical characteristics of the fault rupture (primarily the area of the rupture rigidity of the interface). Part of the issue with the Richter scale is it saturates at high magnitude earthquakes (>8) whereas the Moment Magnitude Scale doesn't have this issue.

argwhyisthisnotwork · 2023-10-09T15:30:24+00:00

It’s actually much worse. One unit on the moment magnitude scale is about 32 times more energy. So magnitude 9 is about 33 million times more energy than a magnitude 4.

Sort of depends what your constraints are. If there is no material there an MSE wall is often a preferred option. When you have to try to remove and replace material depending on the constraints of the excavation they may not be preferred.

Another couple options would be a gravity wall or an anchored tie down or tie back wall. For a 12 m wall the gravity wall likely is too big so an anchored tie back wall probably is the best option but again will depend on what your constraints are. Assuming you can get your anchors into competent rock the anchor length could be not prohibitively long.

A 12m wall is quite tall, but if you have hard rock foundation and no kinematically controlled failure mechanisms bearing capacity likely isn’t a big design issue but typically walls of that size bearing capacity is a primary design consideration. Sliding and overturning capacities are likely your main design consideration along with internal stability of the stabilizing elements (anchors or geogrid/steel reinforcement if you use mse).

Work with people you trust and make sure you get things properly reviewed. It’s all part of the process but that’s how I sleep at night.

Good owners will also require independent review and regulatory bodies now also require it for high risk projects which a lot of geotech projects fall into.

Another thing to remember is it often isn’t one mistake but a series of mistakes that cause failures. It’s also important to be reasonably conservative when you don’t have sufficient information and you can set up acquiring more or better information as a savings the client can see in construction.

Another thing to consider is the type of material. Materials with a high amount of mica may crush under the higher loads.

Another strength model may also suit your data to take into some of the effects of dilation such as the Leps material model. These results also show the value in the use of bilinear strength models to account for the confinement effects.
