1. When calculating NPSHa: Do you use theoretical suction lift 33.9 feet or practical suction lift around 25 feet sea level?
2. I have an 8-inch suction line that is horizontal at the pump location and below the inlet to the pump. the pump is a 3in x 3in so I have a concentric reducer from the...
I like your approach and it is essentially what I have been doing. Get an overall slope angle that is acceptable using a surcharge load for the 4 ft layer. Leave the stability (shallow circles) of the root zone to the water guys.
A sliding block on the interface is also a good idea. I will...
Yes, I thought I might get some of these answers coming from a bunch of geotech's. I am one also. It is controversal. The erosion protection is taken care of.
Generally, it is stream bank stabilization of a 10 to 12 foot (vert) slope to be laid back at my determined slope angle. The stream...
Thanks
I would like to use end bearing and/or a bell. Problem is this is an existing pier group and I have uplift to consider. Can I use blow counts to estimate a phi angle and then a friction coef.
Is there any information on micaceous soils? (e.g. bearing capacity, phi angle, allowable side friction, or lateral soil modulas) Can you use "blow count engineering": my driller did not produce any samples suitable for testing? The stuff feels so greasy I wonder whether there is any side...
