As stability analysis software becomes more sophisticated, we can now realistically incorporate stabilization mitigation methods into the slopes - specifcally - shear pins.
Typicaly we find that shear pins are either driven steel piles or CIP bored piles with either a cage or a beam and CIP's...
As usual - thanks to everyone ahead of time.
The subject is a question that is becoming more complex and more challenging for us folks in Seismic Zone 4 and more financially cripling for those who build using our analyses.
When we have projects that are subject to deep liquefaction and large...
Ladies and gentlemen,
This is the site - 6 acres – flat area on an east/west trending, Southern California, alluvial filled canyon - soil profile transitions from bedrock on the south to dry loose sand to saturated loose sand in the bottom of the canyon (50 feet +-) in a northerly direction -...
Although pre-saturating is part of sample preparation that is performed in laboratories many times a day, this question is both a "how to do it properly and practically", and a research questionaire to identify the state of practice methods used by geotechnical testing laboratories to correctly...
As all of us in Southern California are well aware, this winter will, and already has produced catastrophic mud and debris flows on the hillsides denuded by the wild fires.
In determining the flow velocity, mud concentration and subsequent mud flow rate, I have been unable to find any...
I am looking for good references related to preboring prior to installing and driving precast prestressed concrete piles. The question is 'how large should the diameter of the prebored hole be in relationship to the pile diameter (or cross sectional area)and what effect does the prebore have on...
