It is a gravity rock wall with 3" minus granular backfill. The wall is 10 feet high. Why will the horizontal forces in the wall be different than the horizontal forces in the backfill?
Thanks to all...The Mononobe-Okabe equation was one of the first I looked into for this problem. This site has ROCK on the surface which is an important detail I previously left out. I am the assistant to the chief engineer for this project and the chief believes that during a seismic event...
I am a soils engineer who has never worked in a seismic zone 4 before. I now have a project in zone 4 which has some retaining walls to 10 feet high. For granular retaining wall backfill, I generally give an active pressure of 30 pcf for level backfill and increase that value for sloping...

It is on an island in the pacific ocean. Others are in control of lawyers and non-engineering issues. I am looking for input on the engineering side. Thanx for the good input so far.
I have a client who wants to develop a quarry. He has miles of land with different terrain to choose from. Before I start doing test borings all over the place looking for good rock, I would like to read a book (or maybe a chapter in geotech book) on developing a quarry. Any help??
I am looking for a formula or book to help me estimate settlement of shallow spread foundations in cohesive soil using SPT blowcounts or DCP blowcounts.
