Road Cut Slope Stability - P28 - Stereonet

[@suizrdz]

Oh my gosh!! You just saved my life, thank you so much for this video!!!

[@FREDUgirashebuja]

An open pit rock slope at your mine is intersected by two fault planes and a set of major joints. The dips, dip directions and friction angles of the faults and joint planes are given in the table below: Plane Dip Dip direction Friction angle Fault 1 60° 114° 23° Fault 2 80° 250° 20° Joint set 1 40° 120° 25° The dip and dip direction of the slope are 40° and 164° respectively. Use the stereonet provided to determine whether there is potential instability in the slope. Then using the wedge stability charts provided, determine the factor of safety of the slope. Comment on the confidence you have in the factor of safety determined considering the advantages and disadvantages of the methodology used.

id love a similar video for toppling and another for wedge failures.

Thank you so much - south korea

[@Soilnrock]

Amazing explanation! Beautiful, thanks! 02/12/2020

[@seandunbar3814]

At 3:13 you counted: "10-20-30-50-60?" Think you may have plotted that strike wrong....

[@tareqalbukhari]

You are right 👍

[@carloscuartas3391]

Amazing explanation

[@carloscuartas3391]

Thank you a lot

[@theacademichelper1406]

Thank you very much 🎉

[@farahnazabouk2461]

Very good

[@sayantanghosh6714]

Thank you so much for the great explanations!

what a hero

[@abdulsamad-tr1jw]

How we stabilizing this For increasing the slope of cut or decreasing The friction is it as The bedding plane as it is

[@mohammadrezaahmadi4232]

Why you draw phi from the center? Phi degree should count from the perimeter.

[@rajkirandhiman4208]

Great video Sir. waiting for Direct toppling failure specially. Wedge failure is very clear. Please make video on Direct toppling and flexural toppling. Thanks RK.

[@igorrubio8765]

Thanks for the class. Please give us some nice explanations for the rest of the failure types.

[@arunpratapsingh3652]

V well explained

[@ZE0XE0]

is this only for a plane failure?

[@ipeaceful6]

Very helpful. Thanks!

[@hikikomorihachiman7491]

what is this method called? Equatorial equal method? or pole method? Sir you put strike on 50 instead of 60?

[@mortazapirouz7482]

Correct, 50! I should fix the video.

[@sandipanmitra1685]

Why during the pole plotting of possible planes of failure the stereo is rotated 20 degree each time? How to get frictional angle?

[@ZE0XE0]

frictional angle is determined by testing the rock itself, at what angle two pieces of it start to slide. He chose 20 degrees arbitrarilly because that was as precise as he felt like being. somebody could do it at 1 degree if they wanted, but it would take longer. ultimately it just creates a curved line so as long as you can see the trend and connect the dots with whatever resolution you choose thats all that matters.

[@ketsareeudom2445]

Could you pls tell me how to plot daylight of toppling failue?

[@FREDUgirashebuja]

help

[@tongtongwang]

10 20 30 50 60...where is 40?

[@atulshulka3544]

Sir How to decide friction angle 30 or other
