Culmann's Method

[craigmcg]

Does anybody know where I could find a detailed procedure on how to perform Culmann's method in regards to anchored sheet pile retaining walls? To eliminate any confusion, the procedure I am referring to analyzes the possibility of the anchor inducing a surcharge load on the retaining wall.

Another quick question on the same topic... Would the anchor slab/wall be considered "stable" if the base was below the natural slope (natural slope being a slope at an angle phi from the tip of the retaining wall)?

Thanks!

craigmcg,

Culmann's method is a graphical method using trial and error to locate the critical case for slope stability problems, especially when the backslope has non-uniform geometry.

The Caltrans Trenching and Shoring manual has several worked examples employing this approach and should not be too difficult to locate for download. It also has a good section on trenching and shoring adjacent to railroads, a subject that is not widely discussed in many texts or manuals.

The avaialble passive resistance below the dredge line/toe of the wall depends on the slope angle, spacing of the embedded elements and depth of embedment.

Why don't you try with Talren software, with that you can analise any section that you need.
