Soilder Pile Design - Spacing
Soilder Pile Design - Spacing
(OP)
Can someone provide advice on the use of material properties (friction angle, unit weight)of the retained material to determine lateral spacing of soilder piles? The structural engineer in this instance is asking if the material parameters we have provided can be used to determine the maximum lateral spacing of soilder piles.
The wall in this case, is to retain 3-4m high of an excavation face. Materials to be retained include highly to moderately weathered siltstone and soils.
Any examples, sources would be appreciated.
Thanks

If I'm the structural engineer, I don't like to get friction angles or any of those internal properties. I'd prefer a simple number (usually pcf), so I don't have to look up in my big soil books how to convert them to the pressure per depth.
I looked in my four references for foundation design and couldn't find one with a good design example. The best I could find was a picture of one in Merritt's "Standard Handbook for Civil Engineers"

Also the test program was only test pitting with lab testing only consisting of soil classification tests. The level of investigation was outlined by the structural engineer. This was for a 5 storey building with medium to slightly weathered bedrock at less than 1m depth and on a slope.
