can someone recommend a pdf for borrow pit design? like what methods usually used to stabilized the vertical like sheath piles, etc..
one side of the borrow pit eroded in one of my projects..

0ne to 0ne slope. What do you do after the project is over? find another source of fill to put in the pit?

Cut slopes are usually Ok at 1:1 but fill slopes need flatter grades of 2:1 or even 3:1 for re-compacted material. But where would you get more material to fix your borrow pit? From the borrow pit borrow pit?

I think your borrow pit design might be similar to a waterway design (at low water level) where sheet piles are used to retain the banks. You could investigate the USACoE EMs for design criteria. Here is EM 1110-2-2504 for Sheet Pile design.
To strengthen Sheet Piles in the taller sections, you could add soil nails along the wall. Some are simple drill-in type with a flare end/bearing plate. But just like all galvanized material they eventual corrode. Others are concrete grouted rebar that use bonding to rock and or side wall fraction to resist pullout.
