Hello miss Maria what if we had a soil layer under the base of the wall itself? How would it behave? Would it cause a constant pressure and surcharge only? Please I need an accurate answer. Thank you!
passive soil are always assumed to be not permanently located. At least on what i have read, It is assumed to be excavated along the lifespan of the retaining walls . So, to incorporate this possible future excavation, neglecting it on the analysis and design would add an extra factor of safety for the expected future excavation since passive soil weight and lateral earth pressure contributes to the stablizing force and moment resisting the active earth pressure that tends to overturn the wall.
You are awesome Dr ,keep it up 💞

why the passive verticle force is excluded ?

how's the qu been given??
is it gravity wall or cantiliver wall can you specify that please?
it's a cantilever wall
Miss what if e value is negative? Should I use - for q toe? Or not? If not, then it is okay if q toe > q heel, right? Thank you in advance ❤️
Did u ever get an answer?
How 2/3 of 40???
Thank ma'am
