http://www.aboutcivil.org/answers/3819/total-active-thrust
Determine the total thrust and the point of its appliction for a retaining wall having height of 6 m ,unit weight of soil(backfill) is 20kn/m^2. Angle of internal friction is 16° .The top of soil is kevel with the top of wall horizonal. If the soil carries a udl of 4.5 kn/m^2.Earth Structureshttp://www.aboutcivil.org/answers/3819/total-active-thrustTue, 11 Apr 2017 03:20:00 +0000Residual vs Peak shear strength
http://www.aboutcivil.org/answers/3600/residual-vs-peak-shear-strength
Hey guys, my question is:<br />
<br />
Should you use the residual shear strength or the peak shear strength to calculate the total shearing resistance of the soil when failure takes place along an assumed failure surface?<br />
<br />
I would assume it would depend on the amount of deformation of the soil. If failure is just taking place I'm guessing the soil has probably not deformed enough for it to reach residual strength, in which case it would be best to use peak strength? <br />
<br />
However, I'm guessing using residual strength is more conservative?<br />
<br />
