Lateral Soil Pressure on RC Pile 2

[Upasena]

May I request for some advise on a pile design?
I have a case where 3m of earth filling is coming below the pile head. (Abutment)
On the right side the gravel fill extend to a long distance horizintally. On the left side earth is sloping towards the river at 1:1.5 (vert:horz.)
Pile diameter 1.4 m
How can I calculate the maximum moment and shear force on the pile, from soil on either side?
When calculating the soil force what is the effective soil wedge width?
If there is a particular formula could you please give the reference to it.
Thank you

THere has been some other queries on this - please do a search on the Eng-Tips site. I have referenced a paper by Golder and Seychuk (from an old Pan-Am Soil Conference). Others have referenced more recent. One thread was fairly extensive.

There is an approach that I was that is called Brom's method, it can be found in any good geotechnical engineering handbook.

Basically it assumes full passive pressure is developed behind that resists horizontal shear and overturning moment. What you do is that you assume 9*Cu passive resistance is developed behind the pile and then provide sufficient depth of pile to resist the forces.

Let us know if you need further information and I can post some notes regarding this method.

Thank you very much for the guidance
If possible please send some info to "theuse@sltnet.lk"
