Need some advise regarding sheet pile design
(OP)
Hi friends,
I am working on a sheet pile design project. The height of the sheet pile is 2 to 3 feet. Approximately 11 feet high, 1.5 to 1 reinforced slope is planned for construction behind the sheet pile. The contractor wanted to drive sheet piles in order to minimize the encroachment of buffer zone. my question is, do I need to consider the weight of entire 11 feet high fill material as surcharge for pile design? Or, becuase the sheet pile is only 2 to 3 feet, is it OK if I consider the surcharge load upto 4 t 6 feet behind the sheet pile? If hard/rock encounters shallow depth (say 4 or 5 feet below dredge line), is it ok to terminate the driving sheet pile at that elavation? I will really appreciate if somebody can adivse me on this.

RE: Need some advise regarding sheet pile design
As a VERY rough apoproximation, if you say half the height of the slope would be equivelent to level backfill, your sheeting ht is 2.5=5.5=8 ft. A 4-5 foot toe would require very dense or stiff materials. For medium dense or medium stiff clays, You may need more toe. However, you should run your own numbers.
