Hi, Im writing a spread sheet to calculate immediate settlement using the Burland and Burbridge formula. However Ive come across a problem with the layer thickness correction factor, f1. The equation is as follows:
f1 = H/z1.(2-H/z1)
The problem is that when H/z1 > 2, you get a negative...
Thanks Jim, Another valuable post. Much appreciated. Ive pretty much designed the Navigation piles now and it is obvious they are going to require a fender of some sort to absorb some of the ships energy.
Thanks guys. Think Im getting there. I work as a consultant and there is no way I charge the client the time I spent researching this. Im almost there now but I'll be more careful accepting bespoke jobs next time.
Hi, I’m designing some navigation piles (free ended single laterally loaded piles) to protect a water inlet structure for a water treatment works. The inlet is constructed on the River Thames (UK). The design impact load from a vessel on the river is 100 tonnes at 2.5 meters/second. However I’m...

Hi Im designing some navigation piles (free ended single laterally loaded piles) to protect a water inlet structure for a water treatment works. The inlet is constructed on the River Walton (UK). I need to know the magnitude of force that the navigation piles will be subject from a stray boat...
Im trying to find the empirical equations for base stability of excavations in soft clays, devised by 'O'Rourke from his 1992 publication 'Excavation and Support for the Urban Infrastructure'. Just want the equations not the paper. Thanks
Reinforced concrete CFA Piles have gone in for a structure. There is a problem. The debonding foam around the pile cap rebar has gone 600mm too far beyond the cut off level. Has any one had a similar experience before and if so you could you please tell me how you overcame it.
