Guidance required on Sheet Pile De-Clutching forces

[Grahammachin]

I have posted this in the geotechnical earth retention engineering section but thought I would post here to hoping I could get a response.

I was wondering if anyone could give some guidance on the following:

1. The forces required to declutch a PU32 pile, as a result of the moment applied to the pile?

2. How to calculate the forces in the clutch as a result of the moment?

3. How to calculate the shear capacity of a clutch on a PU32 pile (horizontal shear not vertical)?

The piles have been driven without the clutches being welded up (don't ask...), how much will this affect the load capacity of the piles.

They have been driven to bed rock in clay soils.

Just had some clarification on the problem, maybe not as tricky as I forst thought but could still do with some guidance.

We have 900kNm moment in the pile and they are worried about the in-pan and the outpan sliping in relation to each over vertically as a reuslt of the moment.

Does anyone have any guidance on how to calculate the shear force that I would need to resist

(Would of put this in one post but didn't know how to edit the post)
