Thanks BigH and JD...
I am calculating bearing capacity for 22 feet wide retaining wall footing embeded 3 feet over a soil layer that has a strength of about 500 psf (4 feet layer) over 1500 psf. Each one of the methods result in different answers. Meyerhoff and Hanna (Das' book) results in...
I am looking for references or equations to compute bearing capacity for layered soils.
I have already looked up the following and looking for some more......
1. Myerhoff & Brown, 1960 Geotechnique
2. Myerhoff & Hanna, 1973 Geotechnique & Das's Book
3. Vessic 1973 (Winterkorn and Fang)
4. Army...
